Document Summary
Brain responds with measurable electrical activity when stimulated. Nervous system is a complex communication network in which signals are constantly begin transmitted, received, and integrated. Nervous system is living tissue composed of cells. Cells fall into two major categories: glia and neurons. Neurons are individual cells in the nervous system that receive, integrate, and transmit information. Soma or cell body, contains the cell nucleus and much of the chemical machinery common to most cells. Dendrites are the parts if a neuron that are specialized to receive information. Information flows into the cell body and then travels away from the soma along the axon. Axon is a long, thin fiber that transmits signals away from the soma to other neurons or to muscles or glands. They may branch to other axon to communicate with each other. Axons are wrapped in cells with high concentration of a white, fatty substance called myelin.
