Study Notes
Cranial Nerves
- Cranial nerve 1 (Olfactory nerve) is responsible for the sense of smell.
Vision and Eye Movement
- Cranial nerve 2 (Optic nerve) governs eyesight.
- Cranial nerve 3 (Oculomotor nerve) controls pupil response and other eye movements, originating from the brainstem where the midbrain meets the pons.
- Cranial nerve 4 (Trochlear nerve) controls eye muscles, emerging from the back of the midbrain part of the brainstem.
- Cranial nerve 6 (Abducens nerve) innervates some eye muscles.
Face, Head, and Neck Functions
- Cranial nerve 5 (Trigeminal nerve) is the largest and most complex cranial nerve, with both sensory and motor functions, conveying sensation from the scalp, teeth, jaw, sinuses, and parts of the mouth and face to the brain, and enabling chewing muscles.
- Cranial nerve 7 (Facial nerve) supports face movement, taste, and glandular functions.
- Cranial nerve 11 (Accessory nerve) innervates specific muscles in the head, neck, and shoulder.
Hearing, Balance, and Digestion
- Cranial nerve 8 (Vestibulocochlear nerve) facilitates balance and hearing.
- Cranial nerve 9 (Glossopharyngeal nerve) enables taste, ear and throat movement, and has many more functions.
- Cranial nerve 10 (Vagus nerve) allows sensation around the ear and digestive system, and controls motor activity in the heart, throat, and digestive system.
Tongue Movement
- Cranial nerve 12 (Hypoglossal nerve) supplies motor activity to the tongue.
