Question

Looking at the perineum from the inferior side of the body (so at the foot of the table), what are the boundaries of the perineum?

A) Pubic symphysis and coccyx
B) Ischial tuberosities and coccyx
C) Pubic symphysis and ischial tuberosities
D) Sacrum and coccyx

Answer 1

The perineum is the diamond-shaped space between the pubic symphysis, the coccyx, and the ischial tuberosities. It is divided into superficial and deep layers with some of the muscles common to people of any sex. The boundaries of the perineum when viewed from the inferior side of the body are the pubic symphysis and ischial tuberosities.

Step-by-step explanation:

The perineum is the diamond-shaped space between the pubic symphysis (anteriorly), the coccyx (posteriorly), and the ischial tuberosities (laterally), lying just inferior to the pelvic diaphragm (levator ani and coccygeus).

The perineum is also divided into superficial and deep layers with some of the muscles common to people of any sex.

So, the correct option is C) Pubic symphysis and ischial tuberosities.
