Heart rate, breathing rate and the diameter of blood vessels are controlled by the
Correct answer: D. medulla oblongata
- A. cerebrum
- B. cerebellum
- C. corpus callosum
- D. medulla oblongata
Explanation
The medulla lies at the top of the spinal cord and contains the cardiac, respiratory and vasomotor centres, all of which work without conscious control, so an injury there is very quickly fatal. Because these centres monitor carbon dioxide and blood pressure and correct them, the medulla is a key homeostatic organ. The corpus callosum is only the bundle of fibres joining the two cerebral hemispheres.

About Brain
The brain includes the cerebrum, cerebellum, brainstem, hypothalamus and medulla, each with distinct roles in sensation, movement and homeostasis. Questions connect major brain regions with their functions, reflex control and coordination, while distinguishing involuntary responses from hormonal regulation.
