@atomedgeanatomy: Your brain has a secret: it’s been running your body in the background your whole life.... At the core of your nervous system lies the brainstem and spinal cord, the essential link between thought and action, life and movement. The brainstem, made up of the midbrain, pons, and medulla, is your body’s built-in autopilot, regulating breathing, heartbeat, sleep, and reflexes without you even thinking about it. From there, the spinal cord acts as a high-speed information highway, carrying messages from the brain to every muscle and organ, and relaying sensations back for you to process. Together, they form the foundation of survival, the quiet, tireless network keeping you alive every second of every day. #medtok #anatomynerd #HumanBody #3DAnatomy #anatomy
