The functions of the internal organs are controlled by the ______.

The functions of the internal organs are controlled by the ______.

• A. Medulla
• B. Cerebrum
• C. Cortex
• D. Hippocampus

Answer: (A)

The medulla oblongata, a part of the brainstem, controls the functions of internal organs. It houses the autonomic centers that regulate breathing, heart rate, and blood pressure, and it coordinates reflexes like coughing and swallowing. This part of the brain works automatically to keep essential body processes running without conscious effort. In contrast, the cerebrum and its cortex handle conscious thought, perception, and voluntary movements, not the automatic regulation of internal organs. The hippocampus is involved in memory formation, not autonomic control.
