Q

Describe the true and false pelvises.

A

The true and false pelvises are divide by the arcuate line. The false pelvis is really the lowermost part of the abdominal cavity. It lies between iliac fossae. The true plevis is found inferior to the superior pelvic aperture and contains the pelvic viscera.

Q

What is the pelvic diaphragm and what are its components?

A

The pelvic diaphragm forms the floor of the pelvis and separates the pelvis from the perineum. It is made up of levator ani, coccygeus, and pelvic fascia (parietal and visceral)
