Anal Sphincters and Fecal Incontinence

Although numerous muscles encircle the anal canal, the two that are forensically significant are the internal and the external anal sphincters.

10.4.5.1. Internal Anal Sphincter

This sphincter is a continuation of the circular muscle coat of the rectum and extends 8-12 mm below the dentate line. In the normal living subject, the internal anal sphincter is tonically contracted so that the anal canal is closed. The internal sphincter is supplied by autonomic nerve fibers and is not considered to be under voluntary control (3). Thus, although it appears to contract during a digital assessment of voluntary anal contraction, it is presumed to result from its compression by the surrounding external sphincter fibers (177).
