Suboccipital Muscles 3D

  • Rectus Capitis Posterior Major
    • * Originates from the spinous process of the axis (C2) vertebra.
    • * Inserts onto the occipital bone between the superior and inferior nuchal lines.
    • * Receives its blood supply from the vertebral artery.
    • * Innervated by the suboccipital nerve, a branch of the dorsal ramus of the first cervical spinal nerve (C1).
    • * Functions to extend and rotate the head, as well as provide stability to the upper cervical spine.                                                                                                                                                                                                                                                                                                                                                                                                                           
  • Rectus Capitis Posterior Minor​​​​​​​
    • * Originates from the posterior tubercle of the atlas (C1) vertebra.
    • * Inserts onto the occipital bone between the superior and inferior nuchal lines, just medial to the insertion of the rectus capitis posterior major.
    • * Receives its blood supply from the vertebral artery.
    • * Innervated by the suboccipital nerve.
    • * Functions to extend and rotate the head, as well as provide stability to the upper cervical spine.

 

  • Obliquus Capitis Superior​​​​​​​
    • * Originates from the spinous process of the axis (C2) vertebra.
    • * Inserts onto the transverse process of the atlas (C1) vertebra.
    • * Receives its blood supply from the vertebral artery.
    • * Innervated by the suboccipital nerve.
    • * Functions to laterally flex and rotate the head, as well as provide stability to the upper cervical spine.
