Document Summary

Neurons- individual cells in the nervous system that receive, integrate, and transmit information. Basic links that permit communication within the nervous system. Soma (cell body)- contains the cell nucleus and much of the chemical machinery common to most cells. Dendrites- parts of a neuron that are specialized to receive information. Axon- long, thin fiber that transmits signals away from the soma to other neurons or to muscles or glands. Myelin sheath is the insulating material that encases some axons and that acts to speed up the transmission of signals that move along axons. Terminal buttons- small knobs that secret chemicals called neurotransmitters. Chemicals serve as messengers that may activate nearby neurons. Synapse- junction where information is transmitted from one neuron to another. Information is received at the dendrites, is passed through the soma and along the axon, and is transmitted to the dendrites of other cells at meeting points called synapses.
