Information about Splenius Capitis

Splenius capitis muscle
Muscles connecting the upper extremity to the vertebral column. (Splenius capitis et cervicis labeled at upper right.)
Section of the neck at about the level of the sixth cervical vertebra. Showing the arrangement of the fascia coli. (Splenius capitis labeled at bottom right.)
Latinmusculus splenius capitis
subject #115 397
Origin:Ligamentum nuchae, spinous process of C7-T6
Insertion:Mastoid process of temporal and occipital bone
Artery:
Nerve:C3, C4
Action:Extend, rotate, and laterally flex the head
Dorlands/Elsevier m_22/12550912
The splenius capitis arises from the lower half of the ligamentum nuchæ, from the spinousial process of the seventh cervical vertebra, and from the spinous processes of the upper three or four thoracic vertebræ.

The name derives from the Greek word "spléníon," which means plaster or patch.

The fibers of the muscle are directed upward and lateralward and are inserted, under cover of the Sternocleidomastoideus, into the mastoid process of the temporal bone, and into the rough surface on the occipital bone just below the lateral third of the superior nuchal line.
