Question

Quizplus · Accepted Answer

The cerebellum is responsible for controlling muscular coordination and balance. Damage to the cerebellum can result in difficulties with these functions, as noted in the scenario. The cerebral cortex is responsible for higher-level thinking and perception, and damage to the myelin sheath of the peripheral neurons would primarily affect the transmission of signals through the peripheral nervous system. The pineal gland is involved in the regulation of circadian rhythms and hormone production, and would not likely be implicated in the motor deficits described in the scenario.
