    The sernispinalis (text-fig. 34 B) has an origin from the arti- cular processes of the lower five cervical vertebrae by broad bands, and from the transverse processes of all dorsal vertebrae, the lower fire origins being tendinous. It is inserted into the spinous processes of cervical vertebrae two to six by muscle fibres (sernispinalis colli) and to the seventh cervical and first three dorsal spines by tendons (sernispinalis dorsi). It is practically Text-figure 34. Muscles of the hack. A : com plexus ; B : sernispinalis and suboccipital muscles.

A well-marked muscular slip runs from the third articular process to the transverse process of the atlas and forms a triangle with the inferior oblique and sernispinalis (text-fig. 34, A.O.T). It alters the course of the second and third cervical nerves. The mass of the transverse process of the atlas separates it from the [20]
