interior of cerebrum consists mostly of

Answer 25

white matter

Question 26

white matter in the brain is made up of

Answer 26

association, commissural, or projection fibers

Question 27

association fibers

Answer 27

interconnected areas within one hemisphere

Question 28

commissural fibers

Answer 28

interconnect and permit communication between the 2 hemispheres

projection fibers

Answer 29

link the cerebral cortex to the diencephalon, brainstem, cerebellum, and spinal cord

Question 30

basal nuclei

Answer 30

masses of gray matter embedded deep in white matter of the cerebral hemispheres

Question 31

basal nuclei function

Answer 31

function via a feedback loop to have subconscious control of skeletal muscle tone

Question 32

primary motor cortex
