What is the name of the muscle around the anus?

1. External Anal Sphincter
This muscle is located on the outer side of the anus and, together with the internal anal sphincter on the inner side, constitutes the sphincter system of the anus. The primary function of this system is to control the excretion of feces. The external anal sphincter plays a crucial role in maintaining normal anal function and preventing fecal incontinence.

2. Puborectalis
This muscle is located near the anus and primarily assists in bowel movements and controls defecation. During bowel movements, the puborectalis contracts to help expel feces from the body. If the puborectalis is diseased or damaged, it may lead to bowel dysfunction, requiring prompt medical attention and treatment.

3. Pubococcygeus
This muscle is located in the perineal area and consists of two muscles running downward along both sides of the anus. Its main functions are to assist in bladder emptying and to aid in childbirth.

4. Levator Ani
This muscle is located around the anus and is a thin, wide muscle that forms a ring around the anus and urethra. The levator ani plays a significant role in maintaining the normal function of the anus and urethra.

In addition, there are other muscles such as the piriformis, coccygeus, and ischiocavernosus. If these areas are strained or injured during exercise, medical attention should be sought promptly.
