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.
The rectus abdominis (RA)âthe muscle made famous in movies and televisionâprovides both core stability and trunk mobility (figure 2.9). The RA is a trunk flexor. This muscle arises from the xiphoid process and adjacent costal cartilages, and it attaches distally into the pubic bone at the crest and symphysis.
