Document Summary

Brain stem most primitive regions of brain, and its functions are basic ones. Control of physiological functioning and automatic behaviour (amphibeans have brain stem and simple cerebellum) Cerebral hemispheres constitue large portion of brain. Contains parts of brain that evolved most recently: involved in behaviours of particular interest to psychology. Cerebellum attached to bain of brain, looks like miniature version of cerebral hemispheres. Functions are control and coordination of posture and movement, especially rapid ones. Brain is encased in skull and spinal cord runs through middle of hollow bones (vertebra: vertebral column) Both brain and spinal cord are enclosed in 3 layered set of membrane called meninges float in clear liquid called cerebrospianl fluid (csf) Cerebral cortex outer layer of cerebral hemisphere of brain, approxiamtely. Often referred to as grey matter contains billions of nerve cells (abundant in nerve cell bodies rather than axons) Where perceptions take place,memories are stored, plans are formulated and executed.
