Which part of the human brain controls involuntary actions like blood pressure, salivation, and vomiting?

💡 Solution & Explanation

The medulla oblongata, located in the hindbrain, serves as the primary integration center for autonomic, involuntary physiological activities such as heart rate, respiration, blood pressure, and digestive reflexes like vomiting and salivation. Structures like the cerebrum handle higher cognitive functions and voluntary motor control, whereas the cerebellum coordinates balance and posture.
