A muscle situate at the posterior inferior part of the neck, and at the posterior part of the back. It has a rhomboidal shape, and is attached, by its inner edge, to the posterior cervical ligament, and to the spinous processes of the last cervical vertebrae, and of the first four or five dorsal. By its outer edge, it is attached to the spinal or posterior edge of the scapula. It is divided into two fasciculi, constituting the Rhomhoideus major and Rh. minor, the latter being situate higher than the other. This muscle draws the scapula backwards and upwards, and impresses upon it a rotatory motion, which brings its inferior angle nearer to the spine; and, consequently, depresses the anterior angle and the shoulder.
