-
A very broad (especially anteriorly), thin, flat, irregularly quadrilateral muscle, situate at the sides of the thorax. It is attached, before, to the external surface of the first 8 or 9 ribs, by as many distinct digitations; and, behind, to the spinal edge of the scapula. The superior fibres are almost horizontal; the lower become gradually more and more oblique upwards and backwards. This muscle carries the scapula forwards, and causes it to execute a movement of rotation, which directs its inferior angle forwards, and the anterior upwards. When the shoulder is fixed, it raises the ribs.
