February 2017


Definition

The rectus abdominis muscle is divided into two symmetrical parts and several muscle fiber segments. It is located on the anterior wall of the abdomen, between the breastbone and the pubis. The linea alba passes through the middle of the rectus abdominis muscle. Both sides of the rectus abdominis muscle are surrounded by tendons. It is a high resistance muscle allowing for expiration while protecting the viscera and allowing for the flexion of the trunk and pelvis.
