The mylohyoid is a suprahyoid muscle of the neck. It is a triangular shaped muscle which forms the floor of the oral cavity and supports the floor of the mouth. 

  • Attachments: Originates from the mylohyoid line of the mandible, and attaches onto the hyoid bone.
  • Actions: Elevates the hyoid bone and the floor of the mouth.
  • Innervation: Inferior alveolar nerve, a branch of the mandibular nerve (which is derived from the trigeminal nerve).
  • Blood Supply: Mylohyoid branch of the inferior alveolar artery (itself a branch of the maxillary artery).
