Q
A
  1. Mylohyoid
    Origin: Arises from the mylohyoid line of the mandible.
    Insertion: Attaches to a median fi brous raphe and the body of the
    hyoid bone.
    Action: Elevates the hyoid bone and raises the fl oor of the mouth
    during swallowing, pushing the tongue upward as in swallowing or
    protrusion of the tongue.
    Innervation: By the mylohyoid nerve, a branch of the mandibular
    division of the trigeminal.

Q
A
  1. Geniohyoid

Origin: Inferior mental spine of mandible.
Insertion: Attaches to the body of the hyoid bone.
Action: Slightly elevates and draws the hyoid bone forward,
shortening the fl oor of the mouth. When the hyoid bone remains
fi xed, this muscle also helps retract and depress the mandible.
Innervation: C1 via the hypoglossal nerve (CN XII).

Comment: The digastric, stylohyoid, mylohyoid, and geniohyoid
muscles are considered “suprahyoid” muscles because they lie
above the hyoid bone.

Q
A
  1. Genioglossus

Origin: Arises from the superior part of the mental spine of the
mandible.
Insertion: Dorsum of the tongue and body of the hyoid bone.
Action: Its central fi bers depress the tongue. Its posterior fi bers
protrude the tongue, as in sticking the tongue out of the mouth.
Innervation: Hypoglossal nerve (CN XII).
Comment: The genioglossus is 1 of the 3 extrinsic muscles of the
tongue. These extrinsic muscles move the tongue, whereas the
intrinsic muscles change the tongue’s shape.
All of the muscles with “glossus” in their name are innervated by the
hypoglossal nerve except the palatoglossus muscle, which is not a
tongue muscle but a muscle of the soft palate.
