Description[edit | edit source]
The obliquus capitis superior is a member of the suboccipital group of muscles along with obliquus capitis inferior, rectus capitis posterior major and rectus capitis posterior minor. It is narrow below, wide and expanded above, and is lateral to the semispinalis capitis. It forms the superolateral border of the suboccipital triangle.[1]
Anatomy[edit | edit source]
Origin[edit | edit source]
Superior surface of the transverse process of the atlas (C1)[2]
Insertion[edit | edit source]
Between the superior and inferior nuchal lines of the occipital bone[2]
Nerve Supply[edit | edit source]
Suboccipital nerve or dorsal ramus of cervical spinal nerve (C1)[3]
Blood Supply[edit | edit source]
The muscle receives its blood supply from the vertebral artery and the deep descending branch of the occipital artery.[3]
Function[edit | edit source]
A postural muscle that monitors the position of the head.[3]
Actions[edit | edit source]
Bilaterally, they extend the head; unilaterally, they laterally flex the the head to the same side as the muscle.[2]
