Superficial membranous fascia and the perineal membrane-(moore and dalley, pp 441442.) the blood from straddle injuries is generally limited to the superficial perineal space which is bound by the superficial membranous fascia (superficially; including scarpas fascia on the anterior abdominal wall, dartos fascia on penis and scrotum, and colles fascia on the urogenital triangle) and the deep perineal membrane (deep). the superficial membranous fascia is attached to deep structures at the following locations: superiorly the superficial membranous fascia attaches to the deep fascia of the anterior abdominal muscles about half way between the pubic symphysis and the umbilicus; attaches to the inguinal ligament, and the fascia lata, laterally; and attaches to the posterior edge of the perineal membrane just anterior to the anus campers fascia (answer a) is the fatty layer on the anterior abdominal wall, which extends beyond the umbilicus. transversalis fascia (answer b) is the fascia just deep to the peritoneal lining in the abdomen. dartos fascia (answer c) only covers the scrotum and penis. the inferior fascia of the pelvic diaphragm (answer e) is deep to the perineal membrane.
