Front 14

5 general thalamic functions

primary blood supply to thalamus

Back 16

thalamogeniculate artery branch of the posterior cerebral artery

Front 17

Major side effect of thalamic syndrome

Back 17

increased threshold to all stimuli on OPPOSITE side of body, so you get exaggerated responses; can cause motor paralysis of one side and changes in personality, memory

Front 18

REVIEW

Back 28

no

Front 29

Facial nerve paralysis

Back 29

nuc. of facial nerve is divided into upper and lower half; upper half supplies upper muscles, like the frontalis/orbic. oculi; lower facial = lower face - DAO/bucc.

Front 30

facial nucleus

Back 30

corticobulbar: upper facial - same AND opposite side; lower facial - ONLY opposite side

Front 31

if pt has stroke in LEFT cerebral hemisphere, which part of the nucleus is missing ipsilateral control?

Back 31

lower facial nucleus since it's only controlled by the opposite side. So, pt loses motor control over lower facial muscles (can still wrinkle forehead, cloe eyes hard)

Front 32

If pt has only lower face injury, this means

Back 32

UMN lesion of opposite side

Front 33

pt with facial paralysis and medial strabismus

Back 33

abducent nerve nucleus AND facial nerve paralysis, so lesoin must be in brainstem in facial colliculus

Front 34

facial colliculus is made up of...

Back 34

facial n. fiber and abducent nucleus; LMN injury since it's in nerve fiber, nuclues, or msucle

Front 35

LMN injuries come from

Back 35

nerve fiber, nucleus, musclces

Front 36

UMN injury is where

Back 36

pyramidal tract or cerebral cortex itself
