This is a thin layer of muscular tissue spread over the front of the neck, extending from the breast below, upward, to behind the jaws, and on to the sides of the face.

Below, it is attached to the cariniform cartilage of the sternum, to which it converges from either side. Above, it becomes closely adherent to the muscles in front of the neck, which it braces and supports.
