Although the trigeminal nerve is the predominant sensory nerve of the head there are small areas which are supplied by other cranial nerves:

- Vagus nerve receives sensory signals from the external ear.
- Glossopharyngeal nerve receives sensory signals from the internal surface of the tympanic membrane and also innervates the posterior 1/3rd of the tongue.
