Identify the four pairs of deep muscles of the supoccipital region: rectus capitis (posterior) minor muscle, rectus capitis (posterior) major muscle, superior oblique muscle, and inferior oblique muscle (Figure 1.7). The rectus capitis posterior minor muscle attaches to the inferior nuchal line of the occipital bone and the posterior tubercle of the atlas (C1) vertebra. The rectus capitis (posterior) major and inferior oblique muscles attach to the spinous process of the axis (C2) vertebra. The transverse process of the atlas (C1) is an attachment site for superior and inferior oblique muscles.
