Anterior belly of the digastric is innervated by which nerve?

Explanation:
The anterior belly of the digastric is supplied by a motor branch from the mandibular division of the trigeminal nerve. This branch, the nerve to mylohyoid, comes off the inferior alveolar nerve (a branch of V3) and provides motor innervation to the anterior belly and the mylohyoid muscle. In contrast, the posterior belly is innervated by the facial nerve. The glossopharyngeal and vagus nerves do not innervate these muscles. This connection explains why the anterior belly relies on V3 for its function in assisting jaw opening and hyoid elevation during swallowing.
