| Nerve: | a branch of the dorsal primary division of the suboccipital nerve | |

The Rectus capitis posterior minor (Rectus capitis posticus minor) arises by a narrow pointed tendon from the tubercle on the posterior arch of the atlas, and, widening as it ascends, is inserted into the medial part of the inferior nuchal line of the occipital bone and the surface between it and the foramen magnum, and also takes some attachment to the spinal dura.
The synergists are the rectus capitus posterior major and Obliquus capitis.
