The rectus abdominis muscle (commonly known as "abs") is a paired muscle running vertically on each side of the anterior wall of the human abdomen (and in some other animals). There are two parallel muscles, separated by a band of connective tissue called the linea alba (white line). It extends from the pubic symphysis/pubic crest inferiorly to the xiphisternum/xiphoid process and lower costal cartilages (5-7) superiorly.

The Rectus abdominis is crossed by fibrous bands, three in number, which are named the tendinous inscriptions (or tendinous intersections); one is usually situated opposite the umbilicus, one at the extremity of the xiphoid process, and the third about midway between the xiphoid process and the umbilicus. ...

Function
The rectus abdominis is a key postural muscle. It is responsible for flexing the lumbar spine, as when doing a 'crunch'. The rectus abdominis can play a role in respiration in the event the patient is short of breath. While not moving, a human can be in one of the following main positions. ...
In animal physiology, respiration is the transport of oxygen from the ambient air to the tissue cells and the transport of carbon dioxide in the opposite direction. ...

Location The Rectus abdominis is a long flat muscle, which extends along the whole length of the front of the abdomen, and is separated from its fellow of the opposite side by the linea alba. The linea alba is a fibrous structure that runs down the midline of the abdomen in humans and other animals. ...
 A man with an over-developed abdominal muscles (a "six-pack"). It is much broader, but thinner, above than below, and arises by two tendons; - the lateral or larger is attached to the crest of the pubis,
- the medial interlaces with its fellow of the opposite side, and is connected with the ligaments covering the front of the symphysis pubis.
The muscle is inserted by three portions of unequal size into the cartilages of the fifth, sixth, and seventh ribs. Medial to the pubic tubercle is the pubic crest, which extends from this process to the medial end of the bone. ...
The pubic symphysis is the midline cartilaginous joint uniting the superior rami of the left and right pubic bones (pubis). ...

The upper portion, attached principally to the cartilage of the fifth rib, usually has some fibers of insertion into the anterior extremity of the rib itself.
Some fibers are occasionally connected with the costoxiphoid ligaments, and the side of the xiphoid process. The Costoxiphoid Ligaments (chondroxiphoid ligaments) connect the anterior and posterior surfaces of the seventh costal cartilage, and sometimes those of the sixth, to the front and back of the xiphoid process. ...

Animals
 A feline rectus abdominis muscle, from a common housecat. This specimen has some remaining fascia and also shows the external obliques. The Rectus Abdominis is similar in most vertebrates. The most obvious difference between animal and human abdominal musculature is that in animals, there are a different number of tendinous intersections.
