mylohyoid

The mylohyoid is a paired, flat, triangular muscle that forms the floor of the mouth. Each muscle runs from the inner surface of the mandible to the body of the hyoid bone, and the two sides meet at the midline where a raphe connects them.

Originating from the mylohyoid line on the inner surface of the mandible near the molar teeth, the

Innervation is via the nerve to mylohyoid, a motor branch of the inferior alveolar nerve (branch of
