2024 jamb biology question: Which part of the brain is concerned with reflexes controlling the rate of heartbeat and breathing?

Question: 

Which part of the brain is concerned with reflexes controlling the rate of heartbeat and breathing? (A) medulla (B) cerebrum (C) cerebellum (D) pineal body

Answer:

• Topic: Nervous System / Brain Anatomy & Function
• Explanation: Your brain has different parts with specialized jobs. The cerebrum is for conscious thought, memory, and voluntary actions. The cerebellum coordinates movement and balance. The pineal body deals with sleep cycles. The medulla oblongata, located at the base of the brain connecting to the spinal cord, is crucial because it controls vital involuntary functions – the automatic things you don’t think about, like your heartbeat, breathing rate, blood pressure, swallowing, and sneezing.
• Correct Answer: (A) medulla
