Clinically Relevant Anatomy[edit | edit source]
Anal canal is the end part of the gastrointestinal tract (GIT), it is about 4cm in length in women and more longer in men to be about 4.4 cm in length, passes downwards and backwards forming the anorectal angle. The internal lining mucousa membrane of anal canal divided by the pectinate line into two portions: the upper one the vertical anal columns (8-10 anal fold), at there ends there are valves (anal valves), above each one of these anal valves there is a shallow mucosal pocket called the anal sinus. the lower part below the line is formed of nonkeratinized squamous epithelium with no ducts it is sensitive to pain and provides an internal moisturizing to the canal[1].
The anal canal is described into anatomical and surgical anal canal. The anatomical anal canal starts from the dentate line and ending at the anal verge, while the surgical anal canal extends from the anorectal ring (junction between the anal canal and rectum) to the anal verge[2].
