Pelvic spurs (also known as vestigial legs) are external protrusions found around the cloaca in certain superfamilies of snakes belonging to the greater infraorder Alethinophidia. [1] These spurs are made up of the remnants of the femur bone, which is then covered by a corneal spur, or claw-like structure. [ 1 ]
The pelvic spurs are usually held in the "erect" position and used by the male (at least) to stimulate the female. During mating, the male has a tendency to dig his pelvic spurs into the female's body. Whilst crawling over the female the male's spurs will scratch the surface of the female snake often making a distinct scratching sound.
The rectouterine pouch, being the lowest part of the peritoneal cavity in a woman at supine position, is a common site for the spread of pathology such as ascites, tumour, endometriosis, pus, etc. As it is the furthest point of the abdominopelvic cavity in women, it is a site where infection and fluids typically collect.
The vesicouterine pouch is a fold of peritoneum over the uterus and the bladder, forming a pelvic recess. [1] It is continued over the intestinal surface and body of the uterus onto its vesical surface, which it covers as far as the junction of the body and cervix uteri, and then to the bladder.
Lateral view of a woman's prominent mons pubis. Although present in both men and women, the mons pubis tends to be larger in women. [1] [6] Its fatty tissue is sensitive to estrogen, causing a distinct mound to form with the onset of female puberty. [4] [6] [7] [8] This pushes the forward portion of the labia majora out and away from the pubic ...
The retropubic space is a surgical landmark that has surgical significance in several gynecological and urological procedures. Access to the space is achieved by separating the rectus abdominis muscle at the mid line, and bluntly dissecting the tissue in the direction of the symphysis pubis, until reaching the peritoneum.
The vagina is attached to the pelvic walls by endopelvic fascia. The peritoneum is the external layer of skin that covers the fascia. This tissue provides additional support to the pelvic floor. The endopelvic fascia is one continuous sheet of tissue and varies in thickness. It permits some shifting of the pelvic structures.
The pubic symphysis is a nonsynovial amphiarthrodial joint. The width of the pubic symphysis at the front is 3–5 mm greater than its width at the back. This joint is connected by fibrocartilage and may contain a fluid-filled cavity; the center is avascular, possibly due to the nature of the compressive forces passing through this joint, which may lead to harmful vascular disease.
