• The mylohyoid (also mylohyoid muscle, latin: musculus mylohyoideus) is a paired muscle belonging to the suprahyoid muscles of the neck that extends from the mandible to the hyoid bone.

    Besides moving the hyoid bone, the mylohyoid also participates in forming the oral diaphragm.


    The mylohyoid originates from the mylohyoid line on the internal surface of the mandible.


    The mylohyoid inserts onto the body of the hyoid bone.


    Contractions of the mylohyoid muscle draw the hyoid forward and upward.


    The mylohyoid is innervated by the mylohyoid nerve, a branch of the mandibular division of the trigeminal nerve (CN V3).
