Cranial Nerves Flashcards
Which cranial nerve conducts impulses from the brain to the external eye muscles? It is responsible for lateral movement of the eye.
VI Abducens
Which cranial nerve conducts impulses from the brain to certain shoulder and neck muscles? Its functions include shoulder movements and turning movements of the head.
IX Spinal Accessory
Which cranial nerve conducts impulses from the nose to the brain and is responsible for the sense of smell?
I Olfactory
Which cranial nerve conducts impulses from the brain to muscles of the tongue? Its function is tongue movement.
XII Hypoglossal
Which cranial nerve conducts impulses from the throat and taste buds of the tongue to the brain and from the brain to the throat muscles and salivary glands? Its functions include sensations of the throat, taste, swallowing movements, gag reflex, taste posterior one third of the tongue and secretion of saliva.
IX Glossopharyngeal
Which cranial nerve conducts impulses from the eye to the brain and is responsible for vision?
II Optic
Which cranial nerve conducts impulses from the taste buds of the tongue to the brain and from the brain to facial muscles? Its functions include sense of taste on anterior two thirds of tongue and contraction of muscles of facial expression.
VII Facial
Which cranial nerve conducts impulses from the skin and mucous membrane of the head to the brain; from the teeth to the brain and from the brain to chewing muscles?
Its functions include sensations of face, scalp and teeth and chewing movements.
V Trigeminal
What cranial nerve conducts impulses from the brain to eye muscles and is responsible for eye movements, extraocular muscles,and pupillary control?
III Oculomotor
Which cranial nerve conducts impulses from the brain to the external eye muscles and is responsible for down and inward movements of the eye?
IV Troclear
Which cranial nerve conducts impulses from the ear to the brain and is responsible for hearing and the sense of balance (equilibrium)?
VIII Acoustic (vestibulocochlear)
Which cranial nerve conducts impulses from the throat, larynx, and organs in the thoracic and abdominal cavities to the brain and from the brain to muscles of the throat and organs in the thoracic and abdominal cavities? Its functions include sensations of the throat, larynx and thoracic and abdominal organs; swallowing, voice production, slowing of the heartbeat and acceleration of peristalsis.
