Question | Answer |
---|---|
I | olfactory |
II | optic/ocular |
III | ocularmotor |
IV | trochlear |
V | trigeminal |
VI | abducens |
VII | facial |
VIII | accoustic |
IX | glossopharyngeal |
X | vagus |
XI | spinal |
XII | hypoglossal |
olfactory | connects nose to the brain-sense of smell-sensory |
optic/occular | connects eyes to brain-transmits visual images for the brain to interpret-sensory |
oculomotor | connects brain to eye muscles-moves eyes, raises eyelids, constricts pupils-motor |
trochlear | connects brain to eye-moves upper eyelid, as well as extra occular movements-motor |
trigeminal | connects facial skin, teeth to brain, connects chewing muscles to brain-connects sensation from teeth to brain, transmits motor muscles to jaw for chewing-both |
abducens | connects brain to eye muscles-transmits messages to brain to turn eye outward- motor |
facial | connects taste buds to brain, brain to muscles of face-able to transmit taste from the anterior 2/3 of tongue, move facial muslces for expression as well as send messages to lacrimal and salivary glands-both |
accoustic | connects ear to brain-hearing as well as balance-sensory |
glossopharyngeal | connects tongue and throat to brain, brain to throat and salivary glands-posterior 1/3 of tongue, sends messages to make saliva and swallow-sensory |
vagus | connects pharnyx, larnyx, esophagus, and abd organs to brain-swallow, voice, heart rate, smooth muscle movement, resp and BP-both |
spinal | connects brain to trapezus and sternocleidomastoid- help with movement of these muscles-motor |
hypoglossal | connects brain to the tongue-movement of the tongue-motor |
