Controls eye movements, including pupil constriction and eyelid elevation.

Your nervous system is the silent conductor of every experience you have. By shining a light on these 12 key nerves and giving them the care they deserve, you empower yourself to live with .

The twelve cranial nerves are indispensable to human physiology, bridging the brain’s control over sensory input, motor output, and autonomic functions. Their intricate roles underscore the necessity of preserving their integrity through preventive care and targeted therapies. Continued research into cranial nerve pathways holds promise for innovations in treating conditions ranging from neurodegenerative diseases to cranial nerve tumors.

Responsible for hearing and balance.

To understand how the brain interacts with the body, neurologists categorize these nerves by their primary function: (carrying input to the brain), Motor (sending movement commands from the brain), or Mixed (handling both).
