Pictured above is the sternocleidomastoid (say that one three times real fast). It is a muscle on the front & side of your neck that attaches to the sternum, collar bone, and the back of your skull just behind your ear. It has a lot of influence on proper neck posture.
The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.
