The Anal Canal

Anal canal - Wikipedia

In this article, we shall look at the anatomy of the anal canal — its position, structure, relations and neurovascular supply. The anal canal is located within the anal triangle of the perineum between the right and left ischioanal fossae. It is the final segment of the gastrointestinal tract, around 4cm in length. The canal begins as a continuation of the rectum and passes inferoposteriorly to terminate at the anus.

Anal canal

The anal canal is the terminal segment of the large intestine , between the rectum and anus , located below the level of the pelvic diaphragm. It is located within the anal triangle of the perineum , between the right and left ischioanal fossa. As the final functional segment of the bowel , it functions to regulate release of excrement by two muscular sphincter complexes.
