Sterno-mastoid muscle

March 2018


The sterno-mastoid muscle, or sterno-occipito-mastoid muscle, is found on both sides of the neck. It is attached to the clavicle, sternum, temporal bone, and occipital bone. The sterno-mastoid muscle consists of four plates. The occipital artery, thyroid artery, spinal accessory nerve, and cervical plexus all pass through it. The sterno-mastoid muscle allows for the rotation of the head from side to side and back and forth.
