Which part controls involuntary actions like breathing and heartbeat?

Answer and explanation

Correct answer: Medulla

The governing concept is autonomic or involuntary control by the brainstem. Breathing rhythm and heartbeat continue without conscious decision, and the medulla oblongata contains centres that regulate these vital automatic activities. Therefore, option A is correct. The cerebrum is mainly responsible for conscious thought and voluntary actions, the cerebellum coordinates balance and movement, and the eye is a sensory organ rather than a control centre.
