B
Medulla oblongata
C
Cerebellum
D
Occipital lobe
Verified step by step guidance1
Understand that the autonomic nervous system (ANS) regulates involuntary functions such as heart rate, digestion, and respiratory rate.
Identify the brain regions involved in autonomic control. The thalamus acts mainly as a relay station for sensory information, the cerebellum coordinates movement, and the occipital lobe processes visual information.
Recognize that the medulla oblongata, part of the brainstem, contains vital centers that regulate autonomic functions including heart rate and blood pressure.
Recall that the medulla oblongata houses the cardiac control center, which sends signals via the autonomic nervous system to increase or decrease heart rate as needed.
Conclude that the medulla oblongata is the primary brain region responsible for autonomic regulation of heart rate.
