Study Notes
Cranial Nerves and their Functions
- There are 12 cranial nerves that relay information between the brain and the rest of the body.
Olfactory Nerve (1st)
- Responsible for relaying smell information.
- A sensory nerve that controls the sense of smell.
Optic Nerve (2nd)
- Transmits visual information from the retina to the brain.
- A sensory nerve that controls vision.
Oculomotor Nerve (3rd)
- Controls most eye muscles, including those that move the eye, constrict the pupil, and elevate the upper eyelid.
- Works closely with the Trochlear Nerve (4th) and Abducens Nerve (6th).
Trochlear Nerve (4th)
- Controls the downward and outward movement of the eye.
- Works closely with the Oculomotor Nerve (3rd) and Abducens Nerve (6th).
- Weakness of downward gaze can cause difficulty descending stairs.
Trigeminal Nerve (5th)
- A motor and sensory nerve that carries sensory information from the head, neck, sinuses, and face.
- Supplies muscles used in chewing and sensation in the face.
Abducens Nerve (6th)
- Controls lateral eye movement.
- Works closely with the Oculomotor Nerve (3rd) and Trochlear Nerve (4th).
Facial Nerve (7th)
- A sensory and motor nerve that supplies the muscles of facial expression.
- Controls blinking, taste sensations from the anterior 2/3 of the tongue, and sensation in fingers and toes.
Auditory Nerve (8th)
- Controls hearing and balance.
- The vestibular nerve receives positional information, while the cochlear nerve transmits sound information to the brain.
Glossopharyngeal Nerve (9th)
- A sensory and motor nerve that controls some muscles used in swallowing.
- Controls taste from the posterior one-third of the tongue and sensation in the throat, nasal passages, and tongue.
Vagus Nerve (10th)
- A sensory and motor nerve that controls muscles of the pharynx and larynx.
- Processes sensory information from the external ear, pharynx, larynx, and viscera.
Accessory Nerve (11th)
- A motor nerve that controls muscles used in head and shoulder movement.
Hypoglossal Nerve (12th)
- A motor nerve that controls muscles of the tongue and neck.
- Can cause speech problems, ipsilateral (single-sided) movement of the tongue, and thick speech.
Identify the 12 cranial nerves, their functions, and the senses they control. Test your knowledge of the nervous system and how it interacts with the senses. Learn about the roles of each nerve and how they impact our daily lives.
