Rectus sheath. The rectus sheath is made up of two parts, known as the posterior sheath and the anterior sheath. These sheaths are made of fibers of the transversus abdominis, internal abdominal oblique (IAO), and external abdominal oblique (EAO), which are muscles of the abdomen.
1 Rectus abdominis muscle: originates from the 5th to 7th costal cartilage and the xiphoid process of the sternum and inserts at the pubis (between the pubic tubercle and symphysis). 2  Thereby it passes through the rectus sheath, a tendinous muscle envelope built by the aponeurosis of the lateral abdominal muscles.n particular, the rectus abdominis muscle does a ventral flexion (flexion of the trunk or erection of the pelvis) and thus is an important antagonist of the intrinsic back muscles.
