Origin: Inner surface of the mandible behind the chin (inferior mental spine)
Insertion: Front of the body of the hyoid bone
Action: Pulls the hyoid up and forward; helps lower the mandible
Nerve supply: First cervical nerve via the hypoglossal nerve (C1)

A narrow muscle just above the mylohyoid, beside the midline. It pulls the hyoid forward, widening the throat during swallowing.
