What is primarily regulated by the medulla oblongata?

The medulla oblongata is the lower part of the brain stem and is responsible for regulating basic vital functions, including respiration and heart rate. The cerebellum is responsible for muscular coordination and balance. The cerebrum is responsible for sensory interpretation, thinking, and personality. The thalamus (part of the diencephalon) is responsible for receiving incoming sensory information and routing it to the right part of the cerebrum.
