Document Summary

Neurons: individual cells in the nervous system that receive, integrate, and transmit information, permit communication within the nervous system/ external => internal stimuli, parts of the neuron. Contains the cell"s nucleus and much of the chemical machinery. Parts of the neuron that are specialized to receive information. Dendritic tree: full set of dendrites that handle information exchange (accepting information) Long, thin fiber that functions in the transmission of signals away from the soma -> other neurons or muscles or glands. Wrapped in cells covered with fatty substance known as myelin: myelin sheath insulates the axons and speeds up the signal transmission (signal jumping, loss of muscle control due to myelin sheath degeneration = multiple sclerosis. Ends in cluster of terminal buttons: small knobs which function in the secretion of. The point at which neurons interconnect neurotransmitters. Synapses: junction where information is transmitted from one neuron. Dendrites -> soma -> axon -> dendrites -> etc.
