Which part of the nervous system controls the activities of internal organs________?
Correct answer: D. Medulla Oblongata
- A. Spinal cord
- B. Cerebrum
- C. Cerebellum
- D. Medulla Oblongata
Explanation
The medulla oblongata contains centres that regulate involuntary activities such as breathing, heart rate, and blood pressure, thereby influencing internal organs. The cerebrum handles conscious activities and the cerebellum mainly coordinates movement and balance. Students may choose the spinal cord because it also participates in autonomic control, but among these options the medulla is the main control centre for vital involuntary functions.

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.
