Chapter 14: Cerebral Cortices and the Cerebellum

Question 1

cerebral cortex

Answer 1

the outer edge of gray metter where functioning takes place

Question 2

primary sensory areas

Answer 2

sensory pathways prject to specific regions of the cerebral cortex

Question 3

primary somatosensory cortex

Answer 3

this area of the brain receives general sensory input such as pain, pressure, and temperature from the thalamus

Question 4

association areas

Answer 4

adjacent to primary sensory areas

somatosensory association area

visual association area

Question 5

primary motor cortex

Answer 5

motor pathways from here control many voluntary movements

Question 6

premotor area

Answer 6

the staging area where motor functions are organized before they are initiated in the primary motor cortex.

Question 7

direct pathways

Answer 7

control of muscle tone and conscious fine skilled movements of the face and distal limbs

Question 8

corticospinal

Answer 8

direct control of movements below the head. 75-80% of these tracs decussate. The others

Question 9

corticobulbar

Answer 9

direct control of movements in head and neck

Question 10

cerebellum

Answer 10

helps maintain muscle tone in postural muscles, helps control balance during movement, and coordinate eye movements

Question 11

what are the three functional parts of the cerebellum?

Answer 11

vestibulocerebellum

spinocerebellum

cerebrocerebellum
