Description[edit | edit source]
Musculus splenius cervicis is one of the deep (or intrinsic) muscles of the cervical and thoracic spine. [1] Its fibres run superiorly and laterally. It assists in ipsilateral cervical side flexion and rotation, when both splenius cervicis muscles contract they extend the cervical spine. [2]
Origin[edit | edit source]
Spinous processes of T3 to T6[2]
Insertion[edit | edit source]
Posterior tubercles of transverse processes of C1 to C3.[2]
Nerve Supply[edit | edit source]
Dorsal rami of cervical spinal nerves (C5, 6, 7, and 8)[2]
Blood Supply[edit | edit source]
Muscular branches of the occipital artery from the external carotid artery. Dorsal branches of the posterior intercostal arteries from the thoracic aorta. [3]
Action[edit | edit source]
Bilaterally they extend the neck; unilaterally they laterally flex and rotate the head and neck to the ipsilateral (same) side[3]. [4]
Function[edit | edit source]
Splenius cervicis also assists in supporting the head in the erect position[1]
