Musculus splenius capitis is one of the deep (or intrinsic) muscles of the back. It is a broad straplike muscle in the back of the neck. Deep to Sternocleidomastoid at the mastoid process.[1]
Origin[edit | edit source]
Lower half of Nuchal ligament (C4-C6) and spinous process of C7-T3[2][3]
Insertion[edit | edit source]
Superior nuchal line, Mastoid process of temporal bone, and rough surface adjoining occipital bone[2][3]
Nerve Supply[edit | edit source]
Dorsal ramus of spinal nerves C3-C6[2]
