Olfactory Optic Ocullomotor Trochlear Trigeminal Abducens Facial Vestibulocochlear Glossopharyngeal Vagus Accessory Hypoglossal
Conduct nerve impulses for the sense of smell.
Olfactory Nerve
Carries impulses for vision.
Optic
Pupils change size, shape and equality.
Ability to follow objects, up, down, side to side and diagonally.
Senses changes in light and movement.
Ocullometer Nerve
Carries motor fibers to lateral textual muscle of eye.
Ability to rotate eye interiolateraly.
Trochlear Nerve
Conducts sensory impulses from skin to face and anterior scalp, from mucosae of mouth and nose.
Activates chewing.
Trigeminal Nerve
Carries motor fibers to lateral recrudescence muscle of eye.
Abducens Netve
Supplies motor fibers to muscles of facial expression and to lacrimal and salivary glands.
Carries sensory fibers from taste receptors of anterior tongue.
Facial Nerve
Transmits impulses for senses of equilibrium and hearing.
Vestibulocochlear Nerve
Gag and swallowing reflexes.
Motor fibers serve pharyngeal muscles and salivary glands
Sensory fibers carry impulses from pharynx, posterior tongue and pressure receptors of carotid artery.
