  1. what is the origin of the longus capitis:
    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
  8. what is the insertion of the obliquus capitis inferior:
    inferior surface of the transverse process of C1 (atlas)
  9. what is the action of the obliquus capitis inferior:
    unilateral: ipsilateral rotation
  10. what is the origin of the obliquus capitis superior:
    transverse process of the atlas
  11. what is the insertion of the obliquus capitis superior:
    occipital bone
  12. what is the action of the obliquus capitis superior:

    bilateral:
    unilateral:
    • bilateral: extension of the head on atlas
    • unilateral: ipsilateral rotation
  13. what is the origin of the rectus capitis anterior:
    base of the skull, anterior to the occipital condyle
  14. what is the insertion of the rectus capitis anterior:
    anterior surface of lateral portion of C1 (atlas)
  15. what is the action of the rectus capitis anterior:
    flex head (atlanto-occipital motion)
  16. what is the origin of the rectus capitis lateralis:
    jugular process of the occiput
  17. what is the insertion of the rectus capitis lateralis:
    transverse process of C1 (atlas)
  18. what is the action of the rectus capitis lateralis:
    • flex (atlanto-occipital motion)
    • stabilize the head
  19. what is the origin of the rectus capitis posterior major:
    posterior edge of spinous process of axis
  20. what is the insertion of the rectus capitis posterior major:
    inferior nuchal line on occipital bone
  21. what is the actions of the rectus capitis posterior major:

    bilateral:
    unilateral:
    • bilateral: extension of head on atlas
    • unilateral: ipsilateral rotation
  22. what is the origin of the rectus capitis posterior minor:
    posterior tubercle of axis
  23. what is the insertion of the rectus capitis posterior minor:
    inferior nuchal line on occipital bone (medial aspect)
  24. what are the actions of the rectus capitis posterior minor:

    bilateral:
    unilateral:
    • bilateral: extension of the head on atlas
    • unilateral: ipsilateral rotation
