Document Summary

Neurons are individual conducting cells in the nervous system that receive, integrate, and transmit information. Dendrites are the parts of the neuron that are specialized to receive information, known as receivers spread out and listen in on information from neighboring neurons and pass it on to the cell body. Axon is a long, thin fiber that transmits signals away from the soma to other neurons or to muscles or glands: conducts electrical impulses. o. Portion of the neuron that receives signals and information takes the information from the dendrites and moves it along, almost like an information hideaway. Myelin sheath is insulating material, derived from glial cells, that encases some axons: the myelin sheath speeds up the transmission of signals that move along axons. Terminal buttons that are small knobs that secrete chemicals called neurotransmitters, which are chemicals that transmit information from one neuron to another: these chemicals serve as messengers that activate neighboring neurons.
