what are a few tests that confirm funtionality of CN VII (facial)

Answer 22

show teeth

grimace

tightly close eyes

Question 23

what is UMN lesion

Answer 23

Upper Motor Neuron Lesion -

Results from damage to neuronal cell bodies in the cortex or their axons that project via the corticobulbar tract through the posterior limb of the internal capsule to the motor nucleus of CN VII

Causes loss of voluntary control of only the lower muscles of facial expression on the side _ contralateral_ to the lesion

Question 24

What is a LMN lesion

Answer 24

Lower Motor Neural lession

Results from damage to the motor nucleus of CN VII or its axons

Causes paralysis of all muscles of facial expression (including those of the forehead) ipsilateral to the lesion.
