The hypogastric sheath is a condensation of:
The hypogastric sheath is a condensation of:
Show Hint
It is a deep pelvic condensation carrying vessels to the bladder and uterus.
Updated On: Jun 24, 2026
- Scarpa's fascia
- Colles' fascia
- Pelvic fascia
- Inferior layer of the urogenital diaphragm
Show Solution
The Correct Option is C
Solution and Explanation
Start from where the hypogastric sheath actually lives. It is deep inside the pelvis, slung between the lateral pelvic wall and the pelvic viscera, acting as a conduit for the internal iliac vessels and the nerves heading to the bladder, uterus and rectum.
Anything that sits deep in the pelvis and wraps the pelvic organs has to be part of the pelvic (endopelvic) fascia, because that is the connective-tissue system of the pelvic cavity. The hypogastric sheath is simply a thickened, organised part of that visceral pelvic fascia.
Now rule out the others by location. Scarpa's fascia is up on the lower abdominal wall. Colles' fascia is the membranous fascia of the perineum below. The inferior layer of the urogenital diaphragm, the perineal membrane, is also a perineal structure. All three are outside the pelvic cavity proper, so none can form a pelvic visceral sheath.
That leaves the pelvic fascia as the parent layer.
