The digastric muscle is a small muscle located in the neck, playing a crucial role in the movement of the jaw. It consists of two muscle bellies, the anterior and posterior, connected by an intermediate tendon. This structure allows it to assist in lowering the jaw and elevating the hyoid bone, which is important for swallowing and speaking. The digastric muscle is innervated by two different nerves: the mylohyoid nerve for the anterior belly and the facial nerve for the posterior belly. Its proper function is essential for various activities, including chewing and the overall mechanics of the mouth.
