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
