Considering the functional aspect: – The vertical or lateral bundle, comprising more than half of the optic radiation, corresponds to the macular fibers originating from both hom- onymous hemimaculas. The upper half of the seg- ment represents the upper quadrants and the lower half the lower quadrants. B G The Striate Visual Cortex (Area 17) The striate or visual cortex, also referred to as area 17 of Brodmann, occupies the superior and inferior lips of the calcarine sulcus. It is limited posteriorly by the lunate sulcus, when present, and may extend beyond the occipital pole of the hemisphere for a distance of 1–1. This extension onto the medial posterior aspect of the occipital pole shows important individ- ual variations. The cortex of the visual sensory area is striate and identified histologically by a white line, the line of Gennari, which is a layer of myelinated C terminals of optic radiations fibers, not visible at Fig. An average of 67% of the visual cortex is buried in the depth of the calcarine fissure The striate cortex (area 17) is intimately related to and its branches (Zuckerkandel 1906; Hines 1942; the parastriate cortex (area 18) which lies in a por- Stensaas et al.

From this wide origin it sweeps down in a series of loops: 1to form a sling around the prostate (levator prostatae) or vagina (sphincter vaginae) buy discount atarax 10 mg line anxiety symptoms psychology, inserting into the perineal body; 2to form a sling around the rectum and also insert into order cheap atarax online anxiety symptoms jaw spasms, and reinforce the deep part of buy atarax 10mg visa anxiety symptoms gastrointestinal, the anal sphincter at the anorectal ring (puborectalis); The muscles of the pelvic floor and perineum 133 Fig. It corre- sponds almost exactly with the sacrospinous ligament, which it overlies, and the latter is commonly regarded as a degenerate part of the muscle. Its deep aspect is related to the pelvic viscera and its perineal aspect forms the inner wall of the ischiorectal fossa (see below). The anterior (urogenital) perineum (Figs 98, 99) A line joining the ischial tuberosities passes just in front of the anus. Between this line and the ischiopubic inferior rami lies the urogenital part of the perineum or the urogenital triangle. 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. 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. 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.
