The hypoglossal nerve (XII) controls tongue movement. The vagus nerve (X) is involved in functions like swallowing and speech. The trigeminal nerve (V) is for facial sensation (not taste). The glossopharyngeal nerve (IX) conveys taste from the posterior one - third of the tongue. The facial nerve (VII) has a chorda tympani branch that conveys taste sensation from the anterior two - thirds of the tongue.

Facial nerve (VII)
