Geniohyoid muscle

The video tutorial discusses the geniohyoid muscle, a suprahyoid muscle that forms part of the mouth floor. It covers the muscle's anatomy, including its origin at the mandible's mental spine and insertion at the hyoid bone. The geniohyoid is innervated by the cervical plexus and hypoglossal nerve, aiding in mastication, swallowing, and speech. The video emphasizes the muscle's role in moving the hyoid bone and offers additional resources for further learning.
