The term 'section of the brain' can be broken down into two parts: LOBE and MEDULLA. The LOBE is a four-letter word that refers to a rounded projection of the brain, typically associated with a particular function. The MEDULLA is a seven-letter word that refers to the lower part of the brain stem, which is responsible for controlling vital body functions such as breathing and heart rate. Together, these two sections of the brain are responsible for many of the body's most important functions.
