The Brain and Its Parts
Spinal Cord
This is the infomation superhighway of the body. It carries information up to the brain and instructions back down.
Medulla Oblangata
Helps control the body's autonomic functions (things you don't need to think about to perform) like respiration, digestion and heart rate. Also acts as a relay station for nerve signals going to/from the brain.
Pons
Has roles in your level of arousal or conciousness and sleep. Relays sensory information to/from the brain. Also involved in controlling autonomic body functions.
Cerebellum
Mostly deals with movement. It regulates and coordinates movement, posture and balance. Also involved in learning movement.
