These are twelve in number, and occupy, in two parallel rows, the intervals between the spinous processes of the cervical vertebrae, from that of the atlas and vertebra dentata, to that between the last cervical and first dorsal vertebra. They are flat, thin, and quadrilateral. These muscles contribute to the extension of the neck and to throwing the head backwards.
