Minor core muscles include the latissimus dorsi, gluteus maximus, and trapezius. It is composed of trapezius, latissimus dorsi, rhomboid major, rhomboid minor and levator scapulae. The accessory nerve is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles. The accessory nerve (XI) supplies the sternocleidomastoid and trapezius muscles. The internal carotid artery to reach both the sternocleidomastoid muscles and the trapezius. The superficial layer envelops the trapezius, sternocleidomastoid, and muscles of facial expression. Contraction of the upper part of the trapezius muscle elevates the scapula. The accessory nerve is tested by evaluating the function of the trapezius and sternocleidomastoid muscles. The muscles that perform this function are the rhomboids and the trapezius. Shane (kayfabe) suffered laryngeal contusion, trapezius and rhomboid strains. This is a compound exercise that involves the trapezius, the deltoids and the biceps. Trapezius&colon; originates on the supraspinous ligament and inserts on the spine of the scapula. The superior angle of the scapula or medial angle, is covered by the trapezius muscle. More rarely, the adjoining margins of the sternocleidomastoid and trapezius are in contact. The trapezius and splenius capitis muscle attach to the nuchal ligament.
