Anatomy & Physiology: Muscles—Mylohyoid.

Structure.

• Origin: inner mandibular surface.
• Insertion: body of hyoid.

Function.

• Concentric action: elevates and hyoid and floor of mouth; depresses mandible; head/neck flexion.
• Reverse mover action: elevate hyoid.
• Eccentric action: controls/restrains/slows elevation of mandible, head/neck extension, depression of hyoid.
• Isometric action: stabilizes mandible and hyoid.
• Innervation: mandibular division of trigeminal V nerve.
• Arterial supply: inferior alveolar artery.
