What is the most vital part of the brain, controlling breathing and heart function?

  1. Cerebellum

  2. Hypothalamus

  3. Medulla oblongata

  4. Frontal lobe

The correct answer is: Medulla oblongata

The medulla oblongata is the most vital part of the brain as it controls autonomic functions such as breathing and heart function. The cerebellum primarily controls balance and movement, the hypothalamus regulates body temperature and hormones, and the frontal lobe is responsible for decision making and planning. While all parts of the brain are important, the medulla oblongata is specifically responsible for crucial and life-sustaining functions.
