The external anal sphincter (sphincter ani externus ) is a flat plane of skeletal muscle fibers,

elliptical in shape and Intimately adherent to the skin surrounding the margin of the anus
It is a voluntary sphincter which surround the entire length of the anal canal

It has three parts : subcutaneous, superficial & deep. These parts are separated by fibro-elastic septa
Superficial part: is elliptical in shape , arises from the tips of coccyx and
from anococcygeal raphe and is inserted into perineal body
Superficial part of external Anal sphincter only has Bony Attachment

Deep part: it is annular in shape surrounds the ano-rectal junction . It has no bony attachment
Deep part: posteriorly, it is bend with puborectalis part of levator ani muscle & anteriorly it is inserted into perineal body

Deep part: it is continuous with opposite superficial transverse perineal muscles

The three parts of anal Sphincter perform an effective anal closure Any single part of anal
sphincter is capable of maintaining continence Of solid faeces but notTo fluid or gas
