[edit] Position
It forms a thin investment to the Trapezius, and at the anterior border of this muscle is continued forward as a rather loose areolar layer, covering the posterior triangle of the neck, to the posterior border of the Sternocleidomastoid, where it begins to assume the appearance of a fascial membrane.
Along the hinder edge of the Sternocleidomastoideus it divides to enclose the muscle, and at the anterior margin again forms a single lamella, which covers the anterior triangle of the neck, and reaches forward to the middle line, where it is continuous with the corresponding part from the opposite side of the neck.
In the middle line of the neck it is attached to the symphysis menti and the body of the hyoid bone.
[edit] Existence
It is considered by some sources to be incomplete[1] or nonexistent.[2]
