protects the inner ear from loud noises.
Damage to the pyramidal cells of the cerebral cortex would directly affect
voluntary motor activity.
Damage to the premotor cortex of the frontal lobe would interfere with the ability to
use scissors to cut out a picture.
A tumor that blocks the interventricular foramen in the left cerebral hemisphere would
result in hydrocephalus.
After suffering a blow to the back of the head, Phil becomes comatose. The blow probably caused damage to the
Increased production and release of acetylcholine by the neurons of the cerebral nuclei would result in
spastic, uncontrolled muscle contractions
