Document Summary

Psyc 111 - lecture 4 - neural and hormonal systems: the nervous system. Body"s speedy, electrochemical communication network, consisting of all the nerve cells of the central and peripheral nervous systems. Brain and spinal cord are body"s decision makers. Sensory and motor neurons connecting the cns. Arouses and expends energy and enables voluntary control of skeletal muscles. Calms and conserves energy, allowing routine maintenance activity and controls involuntary muscles and glands. Works a little too slow on occasion but it"s all good. The functional divisions of the human nervous system. Set of glands that secrete hormones into the bloodstream. Hormones travel through the body and affect other tissues, including the brain. The pituitary is the master gland that influences. Scientists can selectively destroy or electrically, chemically, or magnetically stimulate the brain. Less complex brain in primitive vertebrates handle basic survival functions. More complex brain in advanced mammals contain new brain systems built on the old.
