Expert Answer:

Medulla is responsible for maintaining vital body functions, such as breathing, blood pressure and heartrate. The medulla oblongata controls autonomic functions, and relays nerve signals between the brain and spinal cord. It also contains reflex centers of vomiting, salivation, coughing, sneezing, and swallowing.

The main function of the hypothalamus is regulation of the body's internal environment, including water balance, temperature control, feeding behavior, and sleep-wakefulness cycle. In addition to establishing homeostasis, the hypothalamus is responsible for many endocrine functions. Hypothalamus alos has excitatory effects on the autonomic nervous system.
