## Brain Stem

Brain Stem: The brain stem is the oldest part of the brain, located at the base of the skull. It connects the brain to the spinal cord and controls essential functions necessary for our survival, such as breathing, heart rate, and digestion. It also serves as a relay center, transmitting information between the brain and the rest of the body. Additionally, the brain stem regulates our sleep-wake cycles and maintains overall arousal and consciousness. Despite its relatively small size, the brain stem is indispensable imported bodily functions.
