Trigeminal Nerve Cn V

How the Trigeminal Nerve (CN V) Affects Child Development

The trigeminal nerve (CN V) carries facial sensation and powers the chewing muscles, so it underpins a child's feeding, latch and suck, oral-sensory comfort and the oral-motor base for speech. You don't test the nerve at home — you watch the functions it influences, such as comfortable feeding and tolerance of face touch.
