-
A flat muscle; broad, especially below; thin; quadrilateral; and situate at the posterior, lateral, and interior region of the trunk. It is attached to the posterior half of the outer lip of the crest of the ilium; to the posterior surface of the sacrum; to the spinous processes of the six or seven last dorsal vertebrae, to all those of the loins, and to the last four false ribs, and is inserted by a strong tendon at the posterior edge of the bicipital groove of the humerus. Its upper fibres are almost horizontal; the middle very long and oblique upwards and outwards; and the anterior almost vertical. This muscle carries the arm backwards, depressing it, and making it turn on its axis. It also draws backwards and downwards the prominence of the shoulder. When suspended by an arm, we make an effort to raise ourselves, it draws the trunk towards the arm. It can, also, raise the ribs by assuming its fixed point on the humerus, and become an inspiratory muscle.
