The Mylohyoid muscle, flat and triangular, is situated immediately above the anterior belly of the digastric muscle, and forms, with its fellow of the opposite side, a muscular floor for the cavity of the mouth.

It arises from the whole length of the mylohyoid line of the mandible, extending from the symphysis in front to the last molar tooth behind.

The middle and anterior fibers are inserted into a median fibrous raphé extending from the symphysis menti to the hyoid bone, where they joint at an angle with the fibers of the opposite muscle. This median raphé is sometimes wanting; the fibers of the two muscles are then continuous. In general, a raphe (pronounced RAY-fee) is a seam. ... The external surface of the mandible is marked in the median line by a faint ridge, indicating the Symphysis menti or line of junction of the two pieces of which the bone is composed at an early period of life. ...

It is innervated by the mandibular division of the trigeminal nerve, along with the anterior belly of the digastic muscle and the muscles of mastication.

Variations

It may be united to or replaced by the anterior belly of the Digastricus; accessory slips to other hyoid muscles are frequent. The digastric muscle (named digastric as it has two bellies) is a small muscle located under the jaw. ...
