D) Cerebral cortex

Question

Quizplus · Accepted Answer

The vital sign reflexes, such as heart rate, blood pressure, and respiration, are controlled by the brainstem. Therefore, sensory impulses ending in the brainstem may affect these reflexes. The thalamus is involved in sensory processing, but not specifically in controlling vital signs. The cerebellum is involved in motor coordination and balance, and the cerebral cortex is involved in higher functions such as consciousness and perception.
