What does the medulla oblongata do?

The medulla oblongata is the lower portion of the brain stem, adjoining the pons above and the spinal cord below. It aids in communication between the spinal cord and the brain, and between the brain hemispheres. It also plays a role in several autonomic functions, such as respiration and circulation, swallowing and vomiting, urination and defecation, and reflex responses.

A personal observation: “Medulla oblongata” is fun to say, and would be a good name for a band.
