Scalp Muscles

Dr. Rassman,

What are the various muscles of the scalp, and what purpose(s) do they serve? Does the location of these muscles have anything to do with the classic male balding pattern?

There are no muscles actually in or below the scalp except the temporalis muscle extending from the side of the head and somewhat up the sides, the frontalis muscle below the forehead skin, and the occipitalis just in the very back of the head. All of these muscles end (roughly) at the scalp and form a fibrous tendon like fascia called the galea, which covers the bony skull and periosteum.

There is no connection between hair loss and the muscles of the head.
