Information about Rectus capitis posterior minor muscle

Rectus capitis posterior minor muscle
Deep muscles of the back. (Rect. post. minor labeled at top center.)
Latinmusculus rectus capitis posterior minor
subject #116 401
Origin:the tubercle on the posterior arch of the atlas
Insertion:the medial part of the inferior nuchal line of the occipital bone and the surface between it and the foramen magnum
Artery:
Nerve:a branch of the dorsal primary division of the suboccipital nerve
Action:extends the head at the neck, but is now considered to be more of a sensory organ than a muscle
Dorlands/Elsevier m_22/12550468
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.
