Very many muscles in the neck area. Most important one, Sternocleidomastoid. This muscle has 2 heads, one from the sternum, the other from the clavical. Levator scapulae which we can´t really see. Trapezius and then Omohyoid coming from the top-front of the neck to the coracoid on the scapula. If I understood it right. i will find out when I do my homework this coming week.
