1 Subcutaneous Part Corrugator cutis ani is formed by inserting the subcutaneous portion into the perianal skin along with the CLM fibers.

→There are three anatomic components to this sphincter: subcutaneous, superficial, and deep [29].

→Anteriorly it is inserted into the perineal body [29].

→The attachment of the superficial part of the EAS into the coccyx forms the anococcygeal ligament posteriorly.

→It extends from the skin and fascia surrounding the anus and the entire anal canal.

10 EAS (External Anal Sphincter)

→Because of its fan-shaped insertion in the perianal skin, along with fibers of the subcutaneous segment of the EAS, it is responsible for septa formation where external hemorrhoidal plexus is present.

→According to Shafik et al.
, the conjoined longitudinal muscle has a minimal role in maintaining continence [28].

→CLM and extensions divide adjacent tissues into subspaces [27].

→The CLM acts as a skeleton for the external and internal anal sphincter complex, providing support and connecting them.
