What is the nerve supply for the anterior belly of the digastric muscle?

The anterior belly of the digastric muscle is primarily supplied by the mylohyoid nerve, which is a branch of the mandibular nerve (V3). The mylohyoid nerve provides motor innervation to the anterior belly, allowing it to function effectively in activities such as swallowing and mastication.

This specific supply emphasizes the role of the mylohyoid nerve in innervating muscles of the oral cavity. It is crucial for the anterior belly, as it assists in the movement of the mandible and plays a role in the stabilization of the hyoid bone during the swallowing process.

The mylohyoid nerve's connection to the mandibular division of the trigeminal nerve is significant, as the landmarks of this supply highlight the anatomical relevance of the muscles of mastication that are also under the control of the same nerve division. Understanding this nerve supply can help in diagnosing related issues in dental and maxillofacial contexts.
