Description

The muscles of the urogenital triangle are one of the two groups of perineal muscles, the other being the muscles of the anal triangle. The urogenital triangle is defined:

- posteriorly, by an arbitrary line that extends between the right and left ischial tuberosities;

- laterally, by the right and left ischiopubic rami.

The urogenital triangle can be arbitrarily divided into superficial and deep perineal spaces, which are separated by the perineal membrane.

For classification purposes, the muscles of the urogenital triangle can also be arbitrarily divided into two distinct groups:

- muscles of the superficial perineal space;

- muscles of the deep perineal space.
