cerebellum

Question 1

is the cerebellum a UMN

Answer 1

no

Question 2

supratentorial

Answer 2

upper portion of the brain
does not include the cere
for higher order processes- like thinking

Question 17

Inferior cerebellar peduncle is afferent or efferent

Answer 17

afferent

Question 18

ICP afferent pathway

Answer 18

spinal inputs and inferior olivary nucleus fibers to spinocerebellum

Question 19

Middle cerebellar peduncle afferent or efferent

Answer 19

afferent

Question 20

Answer 20

cortex > pontine nuclei >cerebrocerebellum

Question 21

Superior cerebellar peduncle efferent or afferent

Answer 21

both

more efferents then afferents

Question 22
