Posterior belly of the digastric is innervated by which nerve?

Explanation:
The digastric muscle has two bellies with different nerve supplies. The posterior belly originates from the second pharyngeal arch and is innervated by the facial nerve (via its digastric branch). In contrast, the anterior belly comes from the first arch and is supplied by the mandibular division of the trigeminal nerve (nerve to the mylohyoid). So, the posterior belly of the digastric is innervated by the facial nerve.
