Puborectalis muscle

The Puborectalis muscle (pronunciation: pyoo-boh-rek-TAY-lis) is a critical component of the pelvic floor muscles, which support the pelvic organs and help in maintaining continence.

Etymology

The term "Puborectalis" is derived from Latin, where "pubo" refers to the pubic bone and "rectalis" pertains to the rectum.

Function

The Puborectalis muscle forms a sling around the rectum's junction with the anal canal, helping to maintain the anorectal angle. This muscle plays a crucial role in fecal continence, as it relaxes during defecation and contracts to maintain continence.
