Pictured above are the scalene muscles. They lie underneath the sternocleidomastoid, originate along the front & side of your neck, and attach to the first and second ribs. They have a lot of influence on proper neck posture, and are typically "stress muscles."
The image of the muscles is 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.
