Which nerve innervates tensor veli palatini?

Explanation:
The muscle that tenses the soft palate and helps open the auditory tube is innervated by a branch of the trigeminal nerve, specifically from the mandibular division (V3). This nerve, called the nerve to tensor veli palatini, travels with the muscle and provides its motor supply. This is distinct from other soft palate muscles, which receive motor input from the vagus nerve via the pharyngeal plexus. So, the correct innervation is a branch of the trigeminal nerve because tensor veli palatini originates from the first pharyngeal arch and its motor supply comes from V3.
