The muscle extends from the pubic symphysis, pubic crest and pubic tubercle inferiorly, to the xiphoid process and costal cartilages of the 5th–7th ribs superiorly. [1] [2] The rectus abdominis muscle is contained in the rectus sheath, which consists of the aponeuroses of the lateral abdominal muscles.
The linea alba is a white, fibrous band that is made of the bilateral rectus sheaths that join at the anterior midline of the body. These enclose the rectus abdominis muscles (a pair of long, linear muscles, commonly called the “sit-up” muscles) that originate at the pubic crest and pubic symphysis, and extend the length of the body’s trunk.
Diastasis recti, or rectus abdominis diastasis, is an increased gap between the right and left rectus abdominis muscles. [1] The increased distance between the muscles is created by the stretching of the linea alba , a connective collagen sheath created by the aponeurosis insertions of the transverse abdominis , internal oblique , and external ...

The rectus sheath (also called the rectus fascia [1]) is a tough fibrous compartment formed by the aponeuroses of the transverse abdominal muscle, and the internal and external oblique muscles. It contains the rectus abdominis and pyramidalis muscles, as well as vessels and nerves.
The linea alba is formed by the union of aponeuroses (of the muscles of the anterior abdominal wall [2]) that collectively make up the rectus sheath. The linea alba attaches to the xiphoid process superiorly, and to the pubic symphysis inferiorly. It is narrow inferiorly where the two recti abdominis muscles are in contact with each other ...
The rectus abdominis muscle is crossed by three fibrous bands called the tendinous intersections or tendinous inscriptions.One is usually situated at the level of the umbilicus, one at the extremity of the xiphoid process, and the third about midway between the two.
