CRANIAL NERVES OVERVIEW 1
The functional organization of the brain is into a series of
afferents and efferents
The functional organization of the brain is into a series of a) nerves and glia b) afferents and efferents c) reflex arcs
b) afferents and efferents
The roots of the cranial nerves are seen on the a) superior b) inferior surface of the brain
b) inferior
The functional organization of the brain is into a series of afferents and efferents dictates dictate the possible content of both spinal and cranial nerves. Thus, in theory, a nerve can contain... a) Special Sensory b) somatic sensory c) visceral sensory d) somatic motor e) visceral motor/ANS f) Only b and d g) All of the above h) None of the above
g) All of the above

There are sensory only and motor only nerves. True or False (if False what is the correct answer)
False, there are no purely motor cranial nerves
The functional organization of the brain is into a series of afferents and efferents dictates the possible content of spinal nerves but not cranial nerves. True or False (if False what is the correct answer)
False, they dictate the possible content of both spinal and cranial nerves.
