Mylohyoid muscle

This tutorial focuses on the mylohyoid muscle, one of the four suprahyoid muscles, detailing its anatomy, nerve supply, and functions. The mylohyoid muscle forms the oral diaphragm and plays a crucial role in mastication, speech, and swallowing. It is supplied by the mylohyoid nerve from the trigeminal nerve. The video also highlights the muscle's positioning and its contribution to the floor of the mouth. Additional resources for further learning are provided.
