Description:[edit | edit source]

Rectus abdominis is a long muscular strap extending from the ventral lower sternum to the pubis. The muscle is interrupted (but not all the way through) by three (or more) fibrous bands called the tendinous intersections, the most superior intersection is generally at the level of the xiphoid, the lower intersection is at the level of umbilicus and the middle one is at the midway between them.

Origin:[edit | edit source]

It is originated from two tendons inferiorly medial and lateral; 

  • Medial: ligaments covering the front of symphysis pubis 
  • Lateral: the pubis 

Insertion:[edit | edit source]

Sternum (xiphoid process, costoxiphoid ligament)

Ribs 5 to 7 (costal cartilages by three fascicles of differing sizes)

Nerve:[edit | edit source]

Spinal nerves T7 to T12 (ventral rami) 

T7 innervates fibers above the superior tendinous intersection, T8 innervates fibers between the superior and middle intersections and T9 innervates fibers between the middle and lower intersection.
