Anatomical terms of muscle

The longus capitis muscle (rectus capitis anticus major), broad and thick above, narrow below, 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.

It is innervated by a branch of cervical plexus.

Longus capitis has several actions:

acting unilaterally, to:

  • flex the head and neck laterally
  • rotate the head ipsilaterally

acting bilaterally:

  • flex the head and neck [1]
