Document Summary

Brain stem ( older structures") shared with lower order animals. More recently evolved structures (cerebrum) are built atop structures from our distant evolutionary past. Development (embryo) progresses in the same order. Hindbrain comprised of the brain stem (medulla, pons) and cerebellum. Where the spinal cord enters the brain it enlarges to form the stalk-like structure of the brain system. Nerve relay between spinal cord and brain. Contralateral control - left side of brain structure controls right side of the body and right side of the body will control the left side of the body. Nerve relay between higher & lower levels of the nervous system - regulates sleep and muscle control. Rupture would lead to need of life support if not death. State of wakefulness or sleep for sustained periods of time. The area of the brain that most differentiates humans from other animals. Relays sensory information to higher brain centres.
