what does themedulla oblongata do
The medulla oblongata is a cone-shaped neuronal mass responsible for multiple autonomic (involuntary) functions ranging from vomiting to sneezing. The medulla contains the cardiac, respiratory, vomiting and vasomotor centers and therefore deals with the autonomic functions of breathing, heart rate and blood pressure.he medulla can be thought of as being in two parts: 1  an upper open part or superior part where the dorsal surface of the medulla is formed by the fourth ventricle. 2  a lower closed part or inferior part where the fourth ventricle has narrowed at the obex in the caudal medulla, and surrounds part of the central canal.
