The levator veli palatini is innervated by which nerve?

Explanation:
The levator veli palatini elevates the soft palate to close the nasopharynx during swallowing and speech, and its motor supply comes from the pharyngeal plexus carried by the vagus nerve (cranial nerve X). This is why it is innervated by CN X. The other nerves don’t supply this muscle: glossopharyngeal (CN IX) mainly serves stylopharyngeus and sensory areas; facial (CN VII) handles muscles of facial expression; the mandibular division of trigeminal (V3) supplies tensor veli palatini, not the levator. Thus, CN X is the correct innervation.
