Document Summary

Nerves carry both incoming and outgoing information. Sense organs detect changes in the environment and send signals through the nerves to the central nervous system. Brain sends signals though the nerves to the muscles (causing behaviours) Glands produce adjustments in internal physiological processes. Nerve cells, elements of the nervous system that bring sensory information to the brain. Process information and communicate information to other neurons. A cell of central nervous system that provides support for neurons and supplies them with some essential chemicals. Some forms of glial cells form long fibers that guide developing neurons from their place of birth to their final resting place. Other types of glia manufacture chemicals that neurons need to perform their tasks and absorb chemicals that might impair neurons functioning. Dendrites tree like growths attached to the body of a nerve cell, receives messages from other neurons. Dendritic spine a small bud on the surface of a neurons dendrite.
