The medulla is the lowest part of the brain, located at the top of the spinal cord. It controls many of the involuntary functions that keep us alive. For example, the medulla controls our breathing, heart rate, and blood pressure. It's part of the brainstem, which connects the brain to the spinal cord and sends signals between different parts of the body and the brain. In GCSE Biology, understanding the medulla helps explain how the body maintains vital functions without conscious effort.
