Rectococcygeal muscle

Rectococcygeal muscle is a small muscle located in the pelvis region of the human body. It is a part of the musculoskeletal system and plays a role in the functioning of the rectum and the coccyx, also known as the tailbone.

Etymology

The term "rectococcygeal" is derived from the Latin words "rectum" and "coccyx". "Rectum" refers to the final section of the large intestine, while "coccyx" refers to the tailbone, the final segment of the vertebral column.

Anatomy

The rectococcygeal muscle originates from the anterior surface of the coccyx and inserts into the posterior wall of the rectum. It is a thin, flat muscle that is often difficult to distinguish from the surrounding tissues. Despite its small size, the rectococcygeal muscle plays a crucial role in maintaining the position of the rectum and the coccyx.

Function

The primary function of the rectococcygeal muscle is to provide support to the rectum and the coccyx. It helps to maintain the position of these structures within the pelvis. Additionally, the rectococcygeal muscle may play a role in defecation, although this function is not fully understood.

Clinical significance

Due to its location and small size, the rectococcygeal muscle is not commonly involved in medical conditions. However, injury or damage to this muscle can result in pain or discomfort in the coccyx or rectum. Treatment for such conditions typically involves physical therapy or surgical intervention.
