Cranial Nerves _, _, _ are special sense nerves only
I, II, VIII (Olfactory, Optic and, Vestibulocochlear nerves)
Cranial Nerves _, _, _ ALL go to the eye area. Recall that C.N. II (optic) brought input FROM the eye to the brain
III, IV, VI (Oculomotor, Trochlear, Abducens)
Cranial nerves _, _ are the GREAT sensory & motor nerves of the face
V, VII (Trigeminal, Facial nerve)
Carries olfactory input to the brain via the olfactory bulb & tract
C.N I
Much of this input is ultimately interpreted in the uncus of each temporal lobe
Olfactory C.N I
This nerve carries about a million neuron fibers back from the retina of each eye to the brain via the optic nerves, chiasma, and tracts
Optic C.N II
Neurons near the _______ _______ of each occipital lobe serve as sight interpretation.
Calcarine Sulcus
Although often called the auditory nerve it also carries input on the equilibrium from the inner ear.
C.N III Oculomotor
________ & _______ are both involved, thus the name vestibulocochlear nerve
Vestibule & cochlea (C.N III)
Final interpretation of hearing is in the superior temporal gyrus of each temporal lobe
C.N III Oculomotor
There are 6 voluntary (somatic) muscles that allow us to move each eyeball. They work together so we see but one subject rather than having double vision. What are the two C.N.’s that control one of these muscles each?
C.N. IV & VI
IV= Trochlear
VI = Abducens
C.N ___ is more complex & larger & controls 4 of the 6 external eye muscles
C.N III Oculomotor
