Between this line and the ischiopubic inferior rami lies the urogenital part of the perineum or the urogenital triangle discount avodart american express medicine 81. Attached to the sides of this triangle is a tough fascial sheet termed the perineal membrane which is pierced by the urethra in the male and by the urethra and the vagina in the female cheap avodart express symptoms 7 days past ovulation. Deep to this membrane is the external sphincter of the urethra consisting of voluntary muscle fibres surrounding the membranous urethra; these are competent even when the internal sphincter has been completely destroyed buy avodart on line amex symptoms 16 dpo. Enclosing the deep aspect of the external sphincter is a second fascial sheath (comprising areolar tissue on the deep aspect of levator ani), so that this muscle is, in fact, contained within a fascial capsule which is termed the deep perineal pouch. This pouch contains, in addition, the deep transverse perineal muscles and, in the male, the two bulbo-urethral glands of Cowper whose ducts pass forward to open into the bulbous urethra. Superficial to the perineal membrane is the superficial perineal pouch which contains, in the male: 134 The abdomen and pelvis Fig. The urethra is thus enclosed in a spongy sheath supported by a cavernous tube on each side containing thin- walled venous sinuses which become engorged with blood when erection occurs; 3the superficial transverse perineal muscle, running transversely from the perineal body to the ischial ramus. In the female the same muscles are present although much less well developed and the bulbospongiosus is pierced by the vagina. The perineal body This fibromuscular node lies in the midline at the junction of the anterior and posterior perineum. It is the point of attachment for the anal sphincters, the bulbospongiosus, the transverse perineal muscles and fibres of levator ani. The posterior (anal) perineum (Figs 99, 100) This is the triangle lying between the ischial tuberosities on each side and the coccyx. It comprises, in essentials, the anus with its superficial sphinc- ters, levator ani and, at each side, the ischiorectal fossa. It is important to note that the ischiorectal fossae communicate with each other behind the anal canal—infection in one passes readily to the other. Infection of this space may occur from boils or abrasions of the perianal skin, from lesions within the rectum and anal canal, from pelvic infection bursting through levator ani or, rarely, via the bloodstream. The female genital organs The vulva The vulva (or pudendum) is the term applied to the female external genitalia. The labia majora are the prominent hair-bearing folds extending back The female genital organs from the mons pubis to meet posteriorly in the midline of the perineum. The labia minora lie between the labia majora as lips of soft skin which meet posteriorly in a sharp fold, the fourchette. The vestibule is the area enclosed by the labia minora and contains the urethral orifice (which lies immediately behind the clitoris) and the vaginal orifice. The vaginal orifice is guarded in the virgin by a thin mucosal fold, the hymen, which is perforated to allow the egress of the menses, and may have an annular, semilunar, septate or cribriform appearance. At first coitus the hymen tears, usually posteriorly or posterolaterally, and after childbirth nothing is left of it but a few tags termed carunculae myrtiformes. Bartholin’s glands (the greater vestibular glands) are a pair of lobulated, pea-sized, mucus-secreting glands lying deep to the posterior parts of the labia majora. Each drains by a duct 1in long which opens into the groove between the hymen and the posterior part of the labium minus. Anteriorly, each gland is overlapped by the bulb of the vestibule—a mass of cavernous erectile tissue equivalent to the bulbus spongiosum of the male. This tissue passes forwards, under cover of bulbospongiosus, around the sides of the vagina to the roots of the clitoris. Clinical features At childbirth the introitus may be enlarged by making an incision in the perineum (episiotomy). The skin, vaginal epithelium, subcuta- neous fat, perineal body and superficial transverse perineal muscle are incised. The cervix projects into the anterior part of the vault of the vagina so that the continuous gutter surrounding the cervix is shallow anteriorly (where the vaginal wall is 3in (7. This continuous gutter is, for convenience of description, divided into the anterior, posterior and lateralfornices. Relations Anteriorly — the base of the bladder and the urethra (which is em- bedded in the anterior vaginal wall). Having established that there is real shortening present, the examiner must then determine whether this is at the hip, the femur or the tibia, or at a combination of these sites. Place the thumb on the anterior superior spine and the index finger on the greater trochanter on each side; a glance is sufficient to tell if there is any dif- ference between the two sides. With the patient supine, a perpen- dicular is dropped from each anterior superior spine and the distance between this line and the greater trochanter compared on each side. Note that although S3 supplies the posterior part of the scrotum (or vulva), L1 supplies the anterior part of these structures via the ilio-inguinal nerve. The tongue consists of a buccal and a pharyngeal portion separated by a V-shaped groove on its dorsal surface, the. The cervical vertebrae (particularly C7), may be fractured or, more com- monly, dislocated by a fall on the head with acute flexion of the neck, as might happen on diving into shallow water. Dislocation may even result from the sudden forward jerk which may occur when a motorcar or aero- plane crashes. Note that the relatively horizontal intervertebral facets of the cervical vertebrae allow dislocation to take place without their being frac- tured, whereas the relatively vertical thoracic and lumbar interverbral facets nearly always fracture in forward dislocation of the dorsolumbar region. The comparatively thin posterior part of the annulus fibrosus may rupture, either due to trauma or to degenerative changes, allowing the nucleus pulposus to protrude posteriorly into the vertebral canal— the so- called ‘prolapsed intervertebral disc’ (Fig. This may sometimes occur at the lower cervical intervertebral discs (C5/6 and C6/7), very occasion- ally in the thoracic and upper lumbar region or, by far the most commonly, at the L4/5 or L5/S1 disc. Aprolapsed L4/5 disc produces pressure effects on the root of the 5th lumbar nerve, that of the L5/S1 disc on the 1st sacral nerve. Hip flexion with the leg extended (‘straight leg raising’) is painful and limited due to the traction which this movement puts upon the already irritated and stretched nerve root. There may be a weakness of ankle dorsiflexion and numbness over the lower and lateral part of the leg and medial side of the foot (L5) or the lateral side of the foot (S1). If S1 is affected, the ankle jerk may be diminished or absent and there may be weakness of plantar flexion. Occasionally the disc prolapses directly backwards, and, if this is exten- sive, may compress the whole cauda equina, producing paraplegia.

Midline lesions (meningioma, sagittal sinus thrombosis or a gunshot wound) may produce paraplegia by involving both leg areas. Lesions adjacent to the lateral sulcus in either the frontal, parietal or temporal lobes of the dominant hemisphere result in aphasia. The is a large homogeneous mass of grey matter consisting of a , anterior to the interventricular foramen and forming the lateral wall of the anterior horn of the lateral ventricle; a , forming the lateral wall of the body of the ventricle; and an elongated , which forms the roof of the inferior (temporal) horn of the ventricle. The is a roughly ovoid mass closely applied to the lateral aspect of the ; together, they are called the.

Soluble insulin may be mixed in the tients able to set multiple pre-programmed basal insulin syringe with insulin zinc suspensions (amorphous, crystal- rates, and/or temporary infusion rates for such things as line) and with isophane and mixed (biphasic) insulin, and exercise or illness.
