Abdominal Muscle Oblique External

Abdominal oblique muscle

The external oblique abdominal muscle (m. obliquus externus abdominis, pna, bna; m. obliquus abdominis externus, jna) is a paired muscle of the anterior abdominal wall.

It is located most superficially in relation to other abdominal muscles. It originates from the naVIII-XII ribs, from the pedicles of the sternocostal joints of these ribs, from the sheath of the rectus abdominis muscle. The fibers go obliquely downwards and medially, passing into the aponeurosis. The aponeurosis covers the rectus abdominis muscle and, as part of the anterior wall of the rectus abdominis vagina, is attached to the pubic crest and pubic tubercle.

The muscle is involved in flexing the torso and tilting it to the side; strengthens the anterior abdominal wall, takes part in the act of exhalation.

Our life without this muscle would be impossible, we could not even imagine it. It is involved in a large number of processes in our body, which will be discussed below.

The most developed muscle in humans is the rectus muscle. This is one of the muscles in our abdomen that helps support the organs and prevents them from contracting deeply.
