The semispinalis cervicis (semispinalis colli), thicker than the semispinalis dorsi, arises by a series of tendinous and fleshy fibers from the transverse processes of the upper five or six thoracic vertebræ, and is inserted into the cervical spinous processes, from the axis to the fifth inclusive.

The fasciculus connected with the axis is the largest, and is chiefly muscular in structure.
