Musculus mylohyoideus
The mylohyoideus originates from the medial surface of the mandible (mylohyoid line) and inserts on a median fibrous raphe between the two mandibles and on the basihyoid bone. Its action is to elevate the floor of the mouth and the hyoid bone during swallowing and to support the tongue. It is innervated by the mylohyoid nerve (a branch of the mandibular division of the trigeminal nerve, CN V3).
Origin: Medial surface of the mandible (mylohyoid line)
Insertion: Median fibrous raphe between the two mandibles; basihyoid bone
Action: Elevates the floor of the mouth and hyoid bone during swallowing; supports the tongue
Innervation: Mylohyoid nerve (branch of mandibular division of trigeminal, CN V3)
Rarely a primary clinical problem. Relevant mainly in evaluations of swallowing function or after trauma to the floor of the mouth.
Difficulty swallowing or drooling after trauma to the lower jaw should be evaluated.
