Abstract: The anal canal is about 4 cm in length and extends from the anorectal ring (palpable border of anal sphincter and puborectalis muscle) superiorly to the anal verge distally. The anal verge is the junction of the nonkeratinized squamous epithelium of the distal anal canal and the keratinized hair-bearing skin.
