Question

Quizplus · Accepted Answer

The medulla oblongata, located in the brainstem, is responsible for controlling heart rate and blood pressure through the autonomic nervous system. It is specifically the cardiorespiratory center in the medulla oblongata that regulates these functions. The cerebrum is responsible for higher brain functions such as thought and movement, while the cerebellum is responsible for motor control and coordination. The diencephalon includes structures such as the thalamus and hypothalamus, which are important for sensory perception and regulation of hormones, but not specifically for heart rate and blood pressure. The heart itself plays a role in regulating blood pressure through mechanisms such as changes in heart rate and contractility, but the primary control still lies in the brainstem.
