Flashcards in Lec 3-3 Motor Cortex Deck (11):
1

areas for movement of limbs and body

primary motor cortex, dorsal/ventral premotor cortex, supplementary motor area

2

all areas for movement are interconnected, receive blank input, and contribute to corticospinal tract so they are all involved in the blank of movement

thalamic, initiation

3

no muscle contractions or sensations elicited from stimulation

silent cortex

4

using or not using certain motor neurons in the brain results in blank

reorganization because it is very plastic

5

supplementary motor area is involved in blank

bimanual coordination

6

damage to SMA often causes blank

apraxia

7

sma is important in blank tasks

complex and mental rehearsal

8

number of people diagnosed with something each year

incidence

9

number of people alive with something total

prevalence

10

in ALS, these die

upper and lower motor neurons and their axons

11

when an axon dies, scar tissue is left behind which leads to blank

sclerosis
