So called from its resemblance to the spleen of certain animals. A muscle situate at the posterior part of the neck, and upper part of the back. It is much broader above than below, where it terminates in a point. It is attached, by its inner edge, to the spinous processes of the first five dorsal vertebrae; to that of the 7th cervical, and to the inferior part of the posterior cervical ligament. By its upper extremity, it is attached to the transverse processes of the first two cervical vertebrae, to the mastoid process, and to the posterior surface of the occipital bone. Some have considered this muscle to be formed of two portions, which they have ealled Splenitis colli, and Splenius capâ€™itis. The splenius extends the head, inclines it, and rotates it. If the splenii of each side act together, they extend the head.
