Pelvic Plexus
The inferior hypogastric plexus (pelvic plexus in some texts) is a network () of nerves that supplies the organs of the pelvic cavity. The inferior hypogastric plexus gives rise to the prostatic plexus in males and the uterovaginal plexus in females. The inferior hypogastric plexus is a paired structure, meaning there is one on the left and the right side of the body. These are located on either side of the rectum in males, and at the sides of the rectum and vagina in females. For this reason, injury to this structure can arise as a complication of pelvic surgeries and may cause urinary dysfunction and urinary incontinence. Testing of bladder function is used in that case to show a poorly compliant bladder, with bladder neck incompetence, and fixed external sphincter tone. Structure The plexus is formed from: * a continuation of the superior hypogastric plexus on either side, at the Sacrum Promontory in the interiliac triangle. At this location, the presacral nerve sits in the mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelvic Cavity
The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet (the superior opening of the pelvis). Its lower boundary is the pelvic floor. The pelvic cavity primarily contains the reproductive organs, urinary bladder, distal ureters, proximal urethra, terminal sigmoid colon, rectum, and anal canal. In females, the uterus, Fallopian tubes, ovary, ovaries and upper vagina occupy the area between the other organ (anatomy), viscera. The rectum is located at the back of the pelvis, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis. The pelvic cavity also contains major arteries, veins, muscles, and nerves. These structures coexist in a crowded space, and disorders of one pelvic component may impact upon another; for example, constipation may overload the rectum and compress the urinary bladder, or childbirth might damage the pudendal nerves and later lead to Fecal incontinence, anal ...
