Digastric muscle

The video discusses the digastric muscle, a suprahyoid muscle forming the mouth's floor. It has two parts: the anterior and posterior bellies, each with distinct origins and nerve supplies. The anterior belly originates from the digastric fossa and is innervated by the mylohyoid nerve, while the posterior belly originates from the mastoid notch and is innervated by the facial nerve. These muscles aid in chewing, swallowing, and speech, and are crucial for hyoid bone positioning. The digastric muscle also divides the neck's anterior triangle into smaller sections. The video promotes Kenhub as a learning resource.
