What muscles are involved in the semispinalis?

Under the semispinalis capitis and longissimus capitis are four muscles: (1) rectus capitis posterior minor; (2) rectus capitis posterior major; (3) obliquus capitis superior; and (4) obliquus capitis inferior. These muscles connect the skull, atlas, and axis.

What nerve innervates semispinalis capitis?

Semispinalis capitis muscle receives its innervation through the greater occipital nerve (posterior ramus of C2 spinal nerve) and spinal nerve C3. Blood supply comes from the occipital artery that arises from the external carotid artery .

How is m obliquus capitis caudalis positioned?

The m. obliquus capitis caudalis (Fig. 10.6 (12)) is positioned more caudally between the spinous process of the axis and the wing of the atlas; it receives its innervation through the dorsal branch of the second cervical vertebra. Unilateral action provokes rotation of the atlas and thus the head on the dens of the axis.
