The rectus capitis anterior (rectus capitis anticus minor) is a short, flat muscle, situated immediately behind the upper part of the Longus capitis.
It arises from the anterior surface of the lateral mass of the atlas, and from the root of its transverse process, and passing obliquely upward and medialward, is inserted into the inferior surface of the basilar part of the occipital bone immediately in front of the foramen magnum.
origin: anterior surface of the lateral mass of the atlas and the root of its transverse process; insertion: the inferior surface of the occipital bone anterior to the foreamen magnum; action: aids in flexion of the head and the neck; nerve supply: C1, C2. [1]
