Question

What muscle functions to help with fecal continence?

A) Puborectalis muscle
B) Tensor fasciae latae muscle
C) Gluteus maximus muscle
D) Sartorius muscle

Answer 1

The puborectalis muscle helps with fecal continence by being part of the levator ani, supporting pelvic organs and functioning as part of the skeletal muscle sphincters.

Step-by-step explanation:

The muscle that functions to help with fecal continence is the puborectalis muscle. This muscle is part of the levator ani, which is considered the most important muscle of the pelvic floor because it supports the pelvic viscera. These muscles resist intra-abdominal pressure, aid in defecation, and create skeletal muscle sphincters at the urethra and anus to maintain continence.
