Document Summary
Neurons individual cells in the nervous system that receive, integrate, and transmit information. They are basic links that allow communication within the nervous system. Soma cell body of the neuron that contains the nucleus and much of cells normal organs. Dendrite parts of a neuron that receives information. Axon long fiber that transmits information away to other neurons, muscles, or glands. Myelin sheath insulating material that encases some axons. i. Terminal button small knobs where neurotransmitters are transmitted activating neighboring neurons. Synapse junction where information is transmitted from one neuron to another. There is lots of variety among neurons, so not all neurons contain all these parts. Glia cells in nervous system that provides various support for neurons. Glial cells supply nourishment to neurons, remove neurons waste products, and provide insulation around many axons. The neural impulse: using energy to send information. Neural impulse the signal that moves through the neuron.
