Description

Musculus splenius capitis is one of the deep (or intrinsic) muscles of the back. It is a broad strap-like muscle in the back of the neck. Deep to Sternocleidomastoid at the mastoid process.[1]

Origin

Lower half of ligamentum nuchae (C4-C6) and spinous process of C7-T3[2][3]

Insertion

Superior nuchal line, Mastoid process of temporal bone, and rough surface adjoining occipital bone[2][3]

Nerve Supply

Dorsal ramus of spinal nerves C3-C6[2]

Blood Supply

Muscular branches of the occipital artery from the external carotid artery. [2]

Action

Acting bilaterally: extension of the head and cervical spine
Acting unilaterally: lateral flexion of the head and neck and rotation the head to the same side. [3]

Function

It also assists in supporting the head in the erect position[1]

In people with neck pain there may be over activity of superficial muscles and splenius capitis and inhibition of Semispinalis Cervicis[4]

Effective management of neck pain should include exercises that focus on activating Semispinalis Cervicis as well as stretching and myofascial release of the splenius capitis .
