Document Summary

The nervous system: function & structure, everything psychological is biological and physiological, a. Consists of brain and spinal cord: b. Consists of nerves and neurons: both have different function, but work together, works as a communication system. Then is analyzes, organizes and integrates this information. Ns will use this information to instruct parts of the body of what to do: nervous system experiences consciousness. Basic building blocks of neuron system (basic communication unit) They transfer the electrical impulses through the body. They receive information from the environment and send to the. They analyze, organize, and integrate information to produce behavior. They get the information from the interneuron to be carried to other neurons. Soma- controls the entire neuron (function + grow) Dendrite- they expand site of soma to receive information from neurons. Axon: carry information produced by neuron to be delivered. Myelin sheath: white fatty-like sheet (most neurons have it, speeds up transmission and provides insulation.
