Isolation precautions and chemoprophylaxis for exposed individuals if indicated - 25 - 6 risperidone 4mg lowest price. Definition: - involves inflammation of the cerebral cortex - often present with some inflammation of the meninges purchase risperidone 3mg mastercard, i effective risperidone 2 mg. Complications: - seizures - neurologic deficits - 27 - - death Reference: Whitley et. Pearls: - Currant-jelly stools- indicates mixture of blood, mucous and stool, consider Meckel diverticulum or intussusception massive, painless bleeding - Meckel’s Reference: Vox, Victor. Definition: - combination of microangiopathic hemolytic anemia and variable degrees of thrombocytopenia and renal failure - usually occurs ages 6 months-5 years, previously healthy children - most commonly preceded by watery diarrhea that can evolve into hemorrhagic colitis Æ proceeds to hemolysis, thrombocytopenia, then oliguria/anuria several days later 2. Definition: - acute tumor lysis syndrome is the consequence of the rapid release of intra-cellular metabolites (potassium, phosphorus and uric acid) in quantities that exceed the excretory capacity of the kidneys - potential complications include acute renal failure and hypocalcaemia-onset of tumor lysis is most commonly seen at the onset of therapy for malignancies that are especially sensitive to chemotherapy (i. Pathopysiology: - lymphoblasts contain 4 times the content of phosphate of normal - lymphocytes; when the calcium phosphate product exceeds 60, calcium - phosphate precipitates in the renal tubules and microvasculature causing renal failure - 31 - - hyperkalemia can result from tumor lysis or renal failure - an elevation in uric acid results from the breakdown of nucleic acids; urates precipitate in the acid environment of the kidney, causing renal failure - hypocalcaemia occurs secondary to compensatory mechanisms to maintain the calcium phosphate product at 60 3. Definition: - a serious complication of bone marrow transplantation that occurs early in the post- transplant course, with clinical onset usually between day +7 and day +20 - 32 - - clinical syndrome consisting of sudden weight gain, ascites, and hyperbilirubinemia 2. Pathophysiology: - caused by occlusion of the hepatic venules by cellular debris and endothelial swelling related to the toxic effects of the conditioning regimen - results in sclerosis of the terminal hepatic veins which leads to increased resistance and the development of portal hypertension 3. Prevention: - aggressive hydration during pre-conditioning phase to preserve filling pressure and prevent further collapse of the hepatic venules 5. Treatment: - aggressive hydration - renal dose dopamine 3-5 mcg/kg/min to maintain urine output - diuretics i. The onset is 5-10 days after first exposure to heparin and hours to 2-3 days with re-exposure. In re- operative cardiac surgery in adults either the platelets do not rise post-op, or rise, then fall with no other cause evident. Use of alternative anticoagulation is imperative in pre-existing or new thrombosis and should be strongly considered for prophylaxis (up to 50% of asymptomatic patients thrombose). Argatroban, a hepatically excreted, synthetic anti-thrombin with a t 1/2 of ~ 40-50 minutes, is presently our choice. Definition: - inadequate tissue perfusion to supply oxygen and nutrients to meet the metabolic demands of the body - three major types include hypovolemic, distributive and cardiogenic - hypovolemic shock is the most common form, and is due to an absolute loss of volume from the vasculature (blood loss (hemorrhage), body water loss (dehydration) or loss of plasma) - distributive shock results when total circulating volume has been redistributed and a functional hypovolemic state results (seen in sepsis, Neutrogena shock and anaphylaxis) - cardiogenic shock occurs when the heart is unable to maintain cardiac output (may be intrinsic i. Evaluation: rapid evaluation of airway, breathing and circulation Clinical history - underlying disease, recent infection or illness, trauma, surgery, etc. Treatment: - establish a patent airway, ensure adequate oxygenation and ventilation (support cervical spine if trauma suspected) - establish intravascular access - fluid resuscitation (crystalloids i. While the hand skills necessary for performing intubation do take a certain amount of practice, the decision of when to intubate and the choice of technique is of at least equal importance, and is often ignored. While you may not acquire significant “hands on” training in intubating non-neonates during your pediatric residency, you will have the opportunity to learn how to decide when someone should be intubated, as well as the potential complications and problems that may be encountered. Indications for intubation--Thinking about the indications will help you decide on a technique. Requirement for positive pressure ventilation due to pulmonary disease (ie, hypoxia or hypercarbia) C. Paralysis relaxes the pharyngeal muscles, which may obscure landmarks in the difficult airway, and may make bag-mask ventilation difficult. Patients with primary cardiac disease, however, generally do not tolerate unsedated intubations, and carefully titrated anesthesia is warranted. Bag-mask ventilation with cricoid pressure and intubation can generally be accomplished without difficulty. These patients should be intubated “awake” to preserve airway protective reflexes, or by rapid sequence induction with cricoid pressure. Head injury-laryngoscopy and intubation may lead to increased intracranial pressure in the unanesthetized patient with an evolving head injury. Nebulized lidocaine (2cc 1% lidocaine in nebulizer) will decrease the laryngospasm and bronchospasm with intubation. Laryngoscopy and intubation should proceed firmly but gently, with attention to the teeth and tongue if the child is struggling V. Lung disease with moderate to high O2 requirement (may desaturate during period of apnea necessary for rapid sequence intubation) B. Co-administration of a small dose of benzodiazepine will reduce emergence phenomena. Gentle ventilatory assistance through cricoid pressure is sometimes necessary in extremely hypoxic or unstable patients. Common theme-Desire to blunt undesirable physiologic response to intubation-hypertension, tachycardia, bronchospasm, increased intracranial pressure. Technique-rapid sequence refers to rapid infusion of medications, followed by a brief period where airway protective reflexes are lost, followed by ideal intubating conditions. During the period after medications are given, cricoid pressure is applied and positive pressure ventilation is avoided. This is a long time if you can’t get the airway or bag mask ventilate the patient. Cardiovascular-succinylcholine stimulates the vagus nerve and sympathetic ganglia leading to bradycardia, hypertension, or hypotension.
Increased numbers of smudge cells are observed in lymphoproliferative disorders like chronic lymphocytic leukemia cheap risperidone master card. Spur cell anemia An acquired hemolytic condition associated with severe hepatocellular disease such as cirrhosis proven 3mg risperidone, in which there is an increase in serum lipoproteins purchase risperidone paypal, leading to excess of erythrocyte membrane cholesterol.

Teardrop (dacryocytes) Erythrocyte that is elongated at one end to form a teardrop or pear-shaped cell. A teardrop cell cannot return to its original shape because it has either been stretched beyond the limits of deformability of the membrane or has been in the abnormal shape for too long a time. Thrombocytopenia A decrease in the number of platelets in the peripheral blood below the reference range for an individual laboratory (usually below 150 X 109/L). Thrombocytosis An increase in the number of platelets in the peripheral blood above the reference range for an individual laboratory (usually over 440 X 109/ L). Thromboembolism Blockage of a small blood vessel by a blood clot that was formed in the heart, arteries, or veins, dislodged and moved through blood vessels until reaching a smaller vessel and blocking further blood flow. It forms a 1:1 complex with thrombin inhibiting thrombin’s ability to cleave fibrinogen to fibrin but enhances thrombin’s ability to activate protein C.

Alcohol 173 Procedure The middle fnger of the individual to be tested for blood group is cleaned with alcohol and the excess of alcohol is wiped out with sterile cotton cheap 4 mg risperidone visa. A small drop of anti A is added in the portion A cheap risperidone 2mg overnight delivery, anti B in the portion B and anti D in the portion D. A small prick is made on the cleaned fnger, the frst drop of blood coming out is wiped off and second drop of blood is collected directly on the region marked as A, B andD. Immediately, blood is mixed with the corresponding anti antibody by using the sterile stick and observed for any agglutination in the form of clump formation. If the clump is observed in the region marked as A, the blood group is A and the formation of clump in B shows presence of B blood group. The formation of clump in the D region shows presence of Rh positive blood group and if there is no clump formation it shows the presence of Rh negative blood group. Clump formation in the regions A and D shows the presence of A+ blood group and clump formation in the regions B and D shows the presence of B+ blood group. If the clump formation is observed immediately in A blood group type it can be denoted as A type, if it is not immediate then the blood group is of A.

Sinus bradycardia is often seen as a normal variation in athletes, during sleep, or in response to a vagal maneuver. Sinus Arrest or Pause A sinus pause or arrest is defined as the transient absence of sinus P waves that last from 2 seconds to several minutes. The ventricles do not receive regular impulses and contract out of rhythm, and the heartbeat becomes uncontrolled and irregular. Frequently is seen as the last-ordered semblance of a heart rhythm when resuscitation efforts are unsuccessful. Torsades usually terminates spontaneously but frequently recurs and may degenerate into ventricular fibrillation.

Alterations in total circulating plasma volume as well as of total circulating hemoglobin mass determine the hemoglobin concentration discount 3mg risperidone with visa. Reduction in plasma volume 236 Hematology (as in dehydration) may mask anemia or even cause polycythemia buy risperidone 3 mg fast delivery; conversely buy generic risperidone, an increase in plasma volume (as with splenomegaly or pregnancy) may cause anemia even with a normal total circulating red cell and hemoglobin mass. After acute major blood loss, anemia is not immediately apparent since the total blood volume is reduced. It takes up to a day for the plasma volume to be replaced and so for the degree of anemia to become apparent. The initial clinical features of major blood loss are, therefore, due to reduction in blood volume rather than to anemia. Clinical features If the patient does have symptoms, these are usually shortness of breath (particularly on exercise), weakness, lethargy, palpitation and headaches. In older subjects symptoms of cardiac failure, angina pectoris or intermittent claudication or confusion may be present. Visual disturbances due to retinal hemorrhages may complicate very severe anemia, particularly of rapid onset. General signs include pallor of mucous membrane 237 Hematology which occurs if the hemoglobin level is less than 9-10g/ dl. Skin color, on the other hand, is not a reliable sign of anemia; the state of the skin circulation rather than the hemoglobin content of the blood largely determined skin color. The association of features of anemia with excess infections or spontaneous bruising suggests that neutropenia or thrombocytopenia may also be present. Used together, these offer a rational pathophysiologic approach to the laboratory diagnosis of anemia. Physiologic Hypoproliferation Excessive M a t u r a t i o n destruction or loss abnormality of red cell Aplastic anemia Hemolytic anemia Megaloblastic anemias Myelophthisic anemia Blood loss M y e l o d y s p l a s i a , including sideroblastic anemia Renal insufficiency Thalassemia Chronic disease Iron deficiency Endocrine deficiency Stratus 17. Microcytic anemias An important mechanism of anemia is defective hemoglobin synthesis, which results in small, poorly hemoglobinized erythrocytes. After Wright staining, instead of red cells with pink hemoglobin filling the cytoplasm, the cells are pale with only a rim of 239 Hematology hemoglobin. Since hemoglobin is made up of two components, either of two pathophysiologic mechanisms can lead to decrease hemoglobin synthesis-defective heme or decreased globin production. Deficiency of iron store, failure to utilize iron properly, and defective heme or porphyrin synthesis are characteristic of iron deficiency anemia, anemia of chronic disease, and the sideroblastic anemias, respectively. In thalassemia syndromes, globin production is decreased, thereby hindering hemoglobin synthesis and producing a microcytic anemia. Iron deficiency anemia Iron deficiency is the commonest cause of anemia in every country of the world. This is because the body has a limited ability to absorb iron and excess loss of iron due to hemorrhage is frequent. Iron is incorporated form plasma transferrin into developing erythroblasts in the bone marrow and into reticulocytes. Only a small proportion of plasma iron comes from dietary iron absorbed through the duodenum and jejunum. Hemosiderin is an 241 Hematology insoluble protein-iron complex of varying composition containing about 37% of iron by weight. It is probably derived from partial lysosomal digestion of aggregates of ferritin molecules and is visible in macrophages by light microscopy after staining by Perls’ (Prussian blue) reaction. Iron is also present in muscle as myoglobin and in most cells of the body in iron- containing enzymes, e. This tissue iron is less likely to become depleted than hemosiderin, ferritin and hemoglobin in states of iron deficiency, but some reduction of heme-containing enzyme may occur in severe chronic iron deficiency. Dietary iron Iron is present in food as ferric hydroxides, ferric-protein complexes and heme-protein com complexes. Both the iron content and the proportion of iron absorbed differ from food to food; in general, meat and, in particular, liver is a better source than vegetables, eggs or dairy foods. The average Western diet contains 10-15mg of 242 Hematology iron from which only 5-10% is normally absorbed. The proportion can be increased to 20-30% in iron deficiency or pregnancy but, even in these situations, most dietary iron remains unabsorbed. Iron absorption This occurs through the duodenum and less through the jejunum; it is favored by factors such as acid and reducing agents keeping the iron soluble, particularly maintaining it in the ferrous rather than ferric state. Excess iron is combined with apoferritin to form ferritin, which is shed into the gut lumen when the mucosal cell reaches the tip of the intestinal villus. In iron deficiency, more iron enters the cell and a greater proportion of this intramucosal iron is transported into portal blood; in iron overload, less iron enters the cell and a greater proportion of this is shed back into the gut lumen.
These strength tests are common for the skeletal muscles controlled by spinal nerves and are a significant component of the motor exam discount risperidone generic. When light hits the retina purchase discount risperidone on line, specialized photosensitive ganglion cells send a signal along the optic nerve to the pretectal nucleus in the superior midbrain order cheapest risperidone. A neuron from this nucleus projects to the Eddinger–Westphal nuclei in the oculomotor complex in both sides of the midbrain. Neurons in this nucleus give rise to the preganglionic parasympathetic fibers that project through the oculomotor nerve to the ciliary ganglion in the posterior orbit. The postganglionic parasympathetic fibers from the ganglion project to the iris, where they release acetylcholine onto circular fibers that constrict the pupil to reduce the amount of light hitting the retina. Light shined in one eye causes a constriction of that pupil, as well as constriction of the contralateral pupil. Shining a penlight in the eye of a patient is a very artificial situation, as both eyes are normally exposed to the same light sources. If shining the light in one eye results in no changes in pupillary size but shining light in the opposite eye elicits a normal, bilateral response, the damage is associated with the optic nerve on the nonresponsive side. If light in the right eye only causes the left pupil to constrict, the direct reflex is lost and the consensual reflex is intact, which means that the right oculomotor nerve (or Eddinger–Westphal nucleus) is damaged. In that case, the direct reflex is intact but the consensual reflex is lost, meaning that the left pupil will constrict while the right does not. The Cranial Nerve Exam The cranial nerves can be separated into four major groups associated with the subtests of the cranial nerve exam. First are the sensory nerves, then the nerves that control eye movement, the nerves of the oral cavity and superior pharynx, and the nerve that controls movements of the neck. The olfactory, optic, and vestibulocochlear nerves are strictly sensory nerves for smell, sight, and balance and hearing, whereas the trigeminal, facial, and glossopharyngeal nerves carry somatosensation of the face, and taste—separated between the anterior two-thirds of the tongue and the posterior one-third. The oculomotor, trochlear, and abducens nerves control the extraocular muscles and are connected by the medial longitudinal fasciculus to coordinate gaze. Testing conjugate gaze is as simple as having the patient follow a visual target, like a pen tip, through the visual field ending with an approach toward the face to test convergence and accommodation. Along with the vestibular functions of the eighth nerve, the vestibulo-ocular reflex stabilizes gaze during head movements by coordinating equilibrium sensations with the eye movement systems. Motor functions of the facial nerve are usually obvious if facial expressions are compromised, but can be tested by having the patient raise their eyebrows, smile, and frown. Movements of the tongue, soft palate, or superior pharynx can be observed directly while the patient swallows, while the gag reflex is elicited, or while the patient says repetitive consonant sounds. The motor control of the gag reflex is largely controlled by fibers in the vagus nerve and constitutes a test of that nerve because the parasympathetic functions of that nerve are involved in visceral regulation, such as regulating the heartbeat and digestion. Movement of the head and neck using the sternocleidomastoid and trapezius muscles is controlled by the accessory nerve. The cranial nerves connect the head and neck directly to the brain, but the spinal cord receives sensory input and sends motor commands out to the body through the spinal nerves. Whereas the brain develops into a complex series of nuclei and fiber tracts, the spinal cord remains relatively simple in its configuration (Figure 16. From the initial neural tube early in embryonic development, the spinal cord retains a tube-like structure with gray matter surrounding the small central canal and white matter on the surface in three columns. The dorsal, or posterior, horns of the gray matter are mainly devoted to sensory functions whereas the ventral, or anterior, and lateral horns are associated with motor functions. In the white matter, the dorsal column relays sensory information to the brain, and the anterior column is almost exclusively relaying motor commands to the ventral horn motor neurons. The lateral column, however, conveys both sensory and motor information between the spinal cord and brain. Somatic senses are incorporated mostly into the skin, muscles, or tendons, whereas the visceral senses come from nervous tissue incorporated into the majority of organs such as the heart or stomach. The somatic senses are those that usually make up the conscious perception of the how the body interacts with the environment. Testing of the senses begins with examining the regions known as dermatomes that connect to the cortical region where somatosensation is perceived in the postcentral gyrus. To test the sensory fields, a simple stimulus of the light touch of the soft end of a cotton-tipped applicator is applied at various locations on the skin. The spinal nerves, which contain sensory fibers with dendritic endings in the skin, connect with the skin in a topographically organized manner, illustrated as dermatomes (Figure 16. For example, the fibers of eighth cervical nerve innervate the medial surface of the forearm and extend out to the fingers. In addition to testing perception at different positions on the skin, it is necessary to test sensory perception within the dermatome from distal to proximal locations in the appendages, or lateral to medial locations in the trunk.
It is not allowed to provide the sponsor with the original document so that he can make corrections to it discount risperidone 3 mg otc. It is dubious practice to accept advertising for drugs in the book order genuine risperidone, such as full page adverts on the last few pages buy cheap risperidone 3 mg line. Behind the scenes If a potential sponsor does not accept these points, you must abstain from any further co-operation – even if this causes temporary difficulties with the financing of your project. Everyone knows the jokes about the qualified university lecturers working as pharmaceutical sales reps. If you sell yourself you lose your credibility – a flaw which marks some people in our profession for the rest of their lives. Summary Editor/Publisher If you want to pay your co-authors a fee of 25 Euro per page, you have to sell more than 1,000 books. Author Would you have believed that there is so much activity behind the scenes while you are preparing your chapter? Doctor Go on, admit it: after reading this chapter, you almost feel like writing yourself. But please remember what we said at the beginning: clinical textbooks are written in large editorial teams. If you are itching to write, try to gain access to an existing or developing team of authors. You will learn a lot – how book projects are financed, how a publishing 56 Negotiations with sponsors house is registered, and how websites are maintained. Maybe the publishers will even let you in on the secrets of negotiating with sponsors one day. Bystander You suspect conflicts of interest when doctors work together with pharmaceutical companies, don’t you? As you have seen here, it doesn’t have to be that way, but you must be aware of what is allowed and what is not. Also, it is true that someone who is corrupt can enrich himself in the short-term, but in the long-term, the incorruptible are more successful. This is actually a job for the authors, but we prefer the publishers themselves to take on this task. Indexing is not a libidinous task; don’t wait until hundreds of pages are piled up. Creating index entries Mark the word to be included in the index and press Shift-Alt-X (little finger on Shift, thumb on Alt, forefinger on X). After this three- fingered salute, the dialogue window “Define index entry” appears. After possible changes – singular instead of plural; cross reference with “see” – press the return key. Work through the whole text in this way, and finally click on the following symbol in the menu bar (Fig. But before you combine the individual texts to make one document and compile the list of contents and the index, you can inaugurate your website. The home stretch Preliminary publication on the internet There are three good reasons to publish a text on the internet before the book is printed: 1. Some texts are finished earlier than others, which means that the first ones would spend weeks or even months waiting for the rest to be completed. The appearance of the first text on the internet marks the beginning of the advertising campaign for your book. The texts announce a large project and prove that there is activity behind the scenes. Do not expect your readers to be pushing past each other to visit your website on the first day of publication. Websites are available at all times – and the masterminds in the field of web marketing rave about 24-hour presence, 7 days a week. Websites which are unknown can have no better hiding place than the dark cold rooms of the planetary web. As soon as you have published half a dozen chapters, you have also fulfilled the conditions for admission to FreeBooks4Doctors (http://fb4d. As we saw in the first chapter, the best possible advertising campaign for the website is the book, because on the book cover is your internet address (Fig. Please remember that these processes must always be performed in the so-called Normal View (Fig. The section breaks are the horizontal lines which go right across the whole width of the screen in normal view (Fig. These markers contain information for headers and footers and can easily be deleted in the layout view, because you don’t see them there. You need to be very familiar with the individual functions before you can put the headings where you want them.
The nephron cheap risperidone 4mg with visa, the functional unit of the kidney cheap risperidone 4 mg amex, is also a classical epithelial/mesenchyme type of interaction buy risperidone 2mg with visa. The urinary system is developmentally and anatomically associated with genital development, often described as the urogenital system. Adult nephron structure Nephron Development disorganised mesenchymal cells become a highly organised epithelial tubule Condensation - groups of about 100 cells condense tightly together to form a distinct mass Epithelialisation - condensed cells lose their mesenchymal character and gain epithelial At end of this period formed a small epithelial cyst complete with a basement membrane, cell-cell junctions and a defined cellular apico- basal polarity. Bladder Structure Can be described anatomically by its 4 layers from outside inward: Can be described anatomically by its 4 layers from outside inward: Serous - the superior or abdominal surfaces and the lateral" surfaces of the bladder are covered by visceral peritoneum, the serous membrane (serosa) of the abdominal cavity, consisting of mesthelium and elastic fibrous connective tissue. Detrusor Muscle The adult detrusor muscle consists of three layers of smooth Bladder histology (involuntary) muscle fibres. Anatomically can be described in two parts the abdominal part (pars abdominalis) and pelvic part (pars pelvina). The ureter is composed of three layers: outer fibrous layer (tunica adventitia), muscular layer (tunica muscularis) and mucous layer (tunica mucosa). The muscular layer can also be subdivided into 3 fibre layers: an external longitudinal, a middle circular, and an internal longitudinal. During migration from the sacral region the two metanephric blastemas can come into contact, mainly at the lower pole. The kidneys and ureters usually function adequately but there is an increased incidence of upper urinary tract obstruction or infection. Some horseshoe variations have been described as having associated ureter abnormalities including duplications. Urorectal Septum Malformation thought to be a deficiency in caudal mesoderm which in turn leads to the malformation of the urorectal septum and other structures in Horseshoe kidney the pelvic region. Recent research has also identified the potential presence of a persistent urachus prior to septation of the cloaca (common urogenital sinus). There may also be other anomolies associated with failure of closure of abdominal wall and bladder (epispadias, pubic bone anomolies). In diabetes insipidus there is an excretion of large amounts (up to 30 litres/day) of a watery urine and an unremitting thirst (More? The intermediate mesonephros develops and disappears with the exception of its duct, the mesonephric duct, which will form the male reproductive duct system. A few mesonephric tubules remain as efferent ductules in the male and vestigial remnants in the female. Multicystic Kidney - There is no functional kidney tissue present in the kidney and it is replaced by a multilocular cyst. The rests are further characterised by the time of generation leading to different anatomical kidney locations: early intralobar nephrogenic rests (within the renal lobe) and late pelilobar nephrogenic rests (periphery of the renal lobe) (More? Mesonephric duct (Wolffian Duct) and paramesonephric (Mullerian Duct) contribute the majority of male and female internal genital tract respectively. Reproductive development has a long maturation timecourse, begining in the embryo and finishing in puberty. X inactivation occurs randomly throughout the embryo, generating a mosaic of maternal and paternally derived X chromosome activity in all tissues and organs. This population of cells then lie at the hindgut yolk sac junctional region and later migrate into the genital ridge (germinal ridge) in early embryonic development. The mesonephric duct (purple) differentiates under the influence of Testosterone secreted by Leydig cells. Within the testes these mesonephric tubules grow towards the medullary sex cords and will form the rete teste. The medullary sex cords (orange) form testis cords that later differentiate into solid seminiferous tubules which become hollow and actively produce spermatazoa during puberty. The tunica albuginea (white) covers the testis and bands extend inward to form connective tissue septa. In females, it is produced by supporting gonadal granulosa cells and is involved in ovarian follice development. The paramesonephric duct (red, left) grows forming the oviduct (uterine horn) and the end opens into the peritoneal cavity and Infant ovary terminates in fimbria (finger-like extensions). The cortical sex cords (orange) form after the primary sex cords degenerate and mesothelium forms secondary cords. Vagina Development The embryonic origin of the vagina has been a historically hotly debated issue with several different contributions and origins described. Fetal late embryonic male genital development and now in fetal Paramesonephric duct development we will firstly observe early fetal female development. Indifferent stage ‐ cloaca divided by proliferating mesenchyme forming urorecal septum, ventral urethral, dorsal anal pit. Female Genitalia Development This looped animation shows the development of external female genitalia from the indifferent external structure, covering the approximate period of week 9 to 12. The urogenital folds beneath the genital tubercle remain separate (unfused), forming the inner labia minora and second outer skin folds form the larger labia majora either side of the developing vestibule of the vagina. Note at the top of the animation, the Newborn uterus changing relative size of the genital tubercle as it forms the glans of the clitoris.
