0 the muscle that goes from the lower jaw to the hyoid bone (= a bone in the middle of the neck) that forms the floor of the mouth --
The mandibular canal, after the second dentition, is situated just above the level of the mylohyoid line; and the mental foramen occupies the position usual to it in the adult.
The two mylohyoid muscles arise from the mandible at the mylohyoid line, which extends from the mandibular symphysis in front to the last molar tooth behind.
Ia is the submental triangle bound by the anterior bellies of the digastric and the mylohyoid.
Infections, especially odontogenic infections can spread from one space to the other via this communication, or alternatively penetrate the mylohyoid which is a poor barrier to the spread of infection.
The anterior body is supplied by the trigeminal via the mylohyoid nerve, a branch of the inferior alveolar nerve, itself a branch of the mandibular division of the trigeminal nerve.
It is a potential space, and is paired on either side, located on the superficial surface of the mylohyoid muscle between the anterior and posterior bellies of the digastric muscle.
The duct possesses two bends, the first at the posterior border of the mylohyoid muscle and the second near the duct orifice.
Label for mylohyoid nerve is at bottom center.
