👉 The anal weapon, often referred to as the anal sphincter muscles, is a pair of involuntary muscles located at the base of the rectum that play a crucial role in controlling bowel movements and maintaining continence. These muscles consist of an internal sphincter, which is smooth muscle and remains involuntary, and an external sphincter, which is composed of skeletal muscle and is under voluntary control. Together, they work to prevent the involuntary release of feces and maintain bladder control. The internal sphincter tightens when needed to prevent leakage, while the external sphincter can be consciously relaxed or contracted to manage bowel movements. Dysfunction of these muscles can lead to conditions like fecal incontinence or difficulty in controlling bowel movements.
