| Olfactory Nerve Action | sensory, smell |
| Optic Nerve Action | sensory, sight |
| Oculomotor Nerve Action | motor, relays info from brain to effectors
like muscle, involved in eye movements. Cannot move eye down and out, not abduct the eye. Also has autonomic functions (involuntary) like
eyelid elevation, pupil constriction, changes in shape of lens |
| Trochlear Nerve Action | motor, moves eye down and out through depression, abduction, inward rotation |
| Trigeminal Nerve Action | (Trigeminal in General)
mixed, having both sensory and motor fibres. 3 branches that aid in facial, and-teeth, sensation as well as sensation from front and middle third on tongue (anterior 2/3). Motor fibres assist in mastication (biting and chewing) |
| Abducens Nerve Action | motor, last of the 3 nerves involved in eye movement. Abducts the eye |
| Facial Motor Action | Motor controls facial expression. Sensory fibres involved in taste from anterior 2/3 of tongue. Involved in saliva and tear secretion. |
| Vestibulocochlear Motor Action | sensory, hearing and balance |
| Glossopharyngeal Motor Action | sensory, taste and sensation of the posterior 1/3 tongue. Motor fibres involved in swallowing and saliva secretion |
| Vagus Motor Action | aka wandering nerve, supplies a wide range of structures. On sensory side it carries sensation from pharynx, larynx, abdomen…Involved in taste using a flap of tissue at back of the throat known as epiglottis. Motor fibres assist in swallowing and speech. Autonomic functions such as decreasing heart rate, GI tract contractions, sweating |
| Accessory Motor Action | motor, helps shrug shoulders, turn/tilt head |
| Hypoglossal | motor, moves tongue, Intrinsic and extrinsic tongue muscles |
| Trigeminal Ophthalmic Motor Action | sensory, Scalp, forehead, nose |
| Trigeminal Maxillary Motor Action | sensory, cheeks, lower eye lid, nasal mucosa, upper lip, upper teeth and palate |
| Trigeminal Mandibular Motor Action | Sensory: anterior 2/3 tongue, skin over mandible, lower teeth
Motor: muscles of mastication |
