    base of the occiput
  2. what is the insertion of the longus capitis:
    anterior tubercles of C3 - C6 transverse processes
  3. what is the action of the longus capitis:
    flex the head (atlanto-occipital motion)
  4. what is the origin of the longus colli:
    • anterior tubercle of C1
    • bodies of C1 - C3 
    • transverse processes of C3 - C6
  5. what is the insertion of the longus colli:
    • bodies of C5 - T3 vertebrae
    • transverse processes of C3 -  C5 vertebrae
  6. what is the action of the longus colli:
    cervical flexion with rotation to the opposite if unilateral
  7. what is the origin of the obliquus capitis inferior:
    lateral surface of spinous process of axis
