Mylohyoid

  • 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.

    Origin

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

    Insertion

    The mylohyoid inserts onto the body of the hyoid bone.

    Action

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

    Innervation

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