corpus callosum

Question 8

major role of frontal lobe?

Answer 8

planning of physical movement

Question 9

Answer 9

process incoming sensory info

Question 10

major role of temporal lobe?

Answer 10

audition processing

Question 11

major role of occipital lobe?

Answer 11

visual processing

Question 12

cerebellum (location & function)

Answer 12

-under cerebrum
-sends signals to motor cortex
-assists in skilled motor activities

Question 13

brainstem (location, what it includes, function)

Answer 13

-relay centre between brain and spinal cord
-midbrain, pons, medulla
-vital life functions (breathing, heart rate, blood pressure)

Question 14

motor

basal ganglia (location & function)

Answer 14

-near centre of brain
-receives motor info from primary motor cortex
-modify movements; send info back through thalamus

Question 15

thalamus (location & function)

Answer 15

-near centre of brain
-main relay station for sensory info heading to cerebral cortex

Question 16

amygdala (location & function & associations)

Answer 16

-temporal lobe
-emotions, memories, multimodal processing
-sends info to other nuclei in basal ganglia
-associated with autism spectrum disorders

Question 17

Broca’s area (location & function)

Answer 17

-frontal lobe, usually L hemisphere
-speech production & language processing

Question 18

Wernicke’s area (location & function)

Answer 18

-temporal lobe, usually L hemisphere
-language comprehension

Question 19

Arcuate fasciculus

Answer 19

-bundle of nerves connecting B & W’s areas
-important for coordinated and fluid speech

Question 20

motor cortex in context of speech production

Answer 20

coordinates speech movements; sends signals to speech muscles

Question 21

auditory cortex in context of speech production

Answer 21

processing/understanding sounds; monitors and adjusts speech

Question 22

Angular Gyrus (location & function)

Answer 22

-parietal-temporal-occipital junction
-transforming written language to its verbal form

Question 23

supplementary motor area & pre-motor cortex (location & function)

Answer 23

-frontal lobe
-planning complex movements (e.g. speech)
