Urogenital diaphragm
The
urogenital diaphragm is an archaic term describing a layer of the pelvis separating
deep perineal sac from the upper pelvis. Unfortunately, the term is still in common use despite the fact that such a discrete border of the sac probably does not exist.
Nevertheless, the urogenital diaphram usually includes:#
sphincter urethrae muscle (external urethral muscle )#
deep transverse perineal muscle#
superficial transverse perineal muscle#perineal membrane
The urogenital diaphragm is often confused with the
pelvic floor, which is a true diaphragm supporting many of the pelvic organs.
