Description[edit | edit source]
Spinalis Capitis (or Spinalis Colli) belongs to the medial column of the erector spinae (Sacrospinalis) group of muscles.[1] It is the most superior of the spinalis group of muscles with spinalis cervicis and thoracis lying inferiorly in the cervical and thoracic spine.
The spinalis muscles are a group of flat fascicles of varying lengths.[2]
It is known as spinalis capitis due to its attachments to the head (cranium).[2]
Origin[edit | edit source]
Spinous process of C7 -T1.[2]
Insertion[edit | edit source]
Near the midline between superior and inferior nuchal lines of occipital bone.
Nerve Supply[edit | edit source]
Dorsal rami of cervical spinal nerves (C1 to C3).
Blood Supply[edit | edit source]
The muscle receives a blood supply from muscular branches of the vertebral artery via the subclavian and also from muscular branches of the occipital artery via the external carotid artery.
Action[edit | edit source]
Extension of the vertebral column and head.
Function[edit | edit source]
