Study Notes
Cranial Nerves Overview
- Olfactory Nerve: Responsible for the sense of smell; purely sensory function.
- Optic Nerve: Pertains to vision; also a sensory nerve with no motor component.
Eye Movement and Proprioception
- Oculomotor Nerve: Provides proprioception feedback and controls eye movement; engages multiple eye muscles.
- Trochlear Nerve: Focuses on proprioception while facilitating eye movement; specifically innervates the superior oblique muscle.
- Abducens Nerve: Monitors proprioception and allows lateral movements of the eye.
Facial Sensory and Motor Functions
-
Trigeminal Nerve: Major sensory nerve with three branches:
- Ophthalmic: Signals from eyelid and nose.
- Maxillary: Sensations from the cheek skin, upper lip, and palate.
- Mandibular: Carries sensations from the tongue (without taste) and lower teeth; motor function includes muscles used for mastication.
- Facial Nerve: Involved with taste perception from taste buds and controls facial expressions through motor signals.
Hearing and Balance
- Vestibulocochlear Nerve: Responsible for hearing and balance; contains a motor component that fine-tunes sensory sensitivity.
Swallowing and Tongue Movement
- Glossopharyngeal Nerve: Provides taste sensation and motor control for tongue movement and swallowing.
- Vagus Nerve: Involved in taste, speech, and swallowing; regulates motor functions of skeletal muscles in the pharynx and larynx.
Additional Motor Controls
- Accessory Nerve: Engages in proprioception for neck movement, and controls head, neck, and shoulder motor actions.
- Hypoglossal Nerve: Facilitates proprioception and governs tongue movements critical for speech and swallowing.
