Study Notes
Cranial Nerves
- Cranial nerves are part of the peripheral nervous system, carrying signals between the brain and the body.
- There are 12 pairs of cranial nerves.
- Each nerve has a specific function and carries different types of information.
Cranial Nerve Functions
- Olfactory (I): Sensory, smell
- Optic (II): Sensory, vision
- Oculomotor (III): Motor, eye movement (most extrinsic eye muscles), pupil constriction
- Trochlear (IV): Motor, eye movement (superior oblique muscle)
- Trigeminal (V): Mixed, sensory from face (touch, pain, temperature), motor to chewing muscles
- Abducens (VI): Motor, eye movement (lateral rectus muscle)
- Facial (VII): Mixed, sensory from taste buds on anterior 2/3 of tongue, motor to facial muscles, salivary glands
- Vestibulocochlear (VIII): Sensory, hearing and balance
- Glossopharyngeal (IX): Mixed, sensory from taste buds on posterior 1/3 of tongue, motor to pharyngeal muscles, salivary glands
- Vagus (X): Mixed, sensory from visceral organs, motor to visceral organs, parasympathetic innervation
- Accessory (XI): Motor to shoulder and neck muscles
- Hypoglossal (XII): Motor, tongue muscles
Additional Notes
- Some nerves are purely sensory (carrying only input information).
- Others are purely motor (carrying only output information).
- Many cranial nerves are mixed, carrying both sensory and motor information.
