Longus capitis muscle
Muscle of neck
From Wikipedia, the free encyclopedia
The longus capitis muscle (Latin for long muscle of the head, alternatively rectus capitis anticus major) is broad and thick above, narrow below, and arises by four tendinous slips, from the anterior tubercles of the transverse processes of the third, fourth, fifth, and sixth cervical vertebræ, and ascends, converging toward its fellow of the opposite side, to be inserted into the inferior surface of the basilar part of the occipital bone.
