in the middle

26

Gray matter equals what?

neuronal cell bodies

27

White matter is what?

tracts; axons and dendrites

28

Where is the Olfactory Nerve located?

Right behind the nasal bone: microscopic structure send nerves through cribiform plate, NOT really the OLFACTOrY bulb

What nerves are affected by pituitary tumors?

Optic II and Olfactory I

36

Where does the vestibulocochlear nerve emerge from?

From the base of brain at junction of pons and medulla = pontomedullary jnx

37

Where are the vestibulocochlear organs located?

petrous part of the temporal bone

38

Where is the CN VIII sent through?

Interal acoustic meatus then into brain stem and enter the brain stem and terminate on nuclei in the deep white matter of brain stem

39

Vestibular portion of CN VIII innervates

vestibular apparature for balance and equilibrium

Cochlear portion of CN VIII innervates

cochlear apperature and for sense of hearing
