Document Summary

1- central nervous system: brain, spinal cord. Two classes of cells in the cns; neurons, which process information and glia, which provide the neurons with mechanical and metabolic support. 2- peripheral nervous system: skeletal nervous system. Cell body contains structures that maintain cell health and metabolism. Nucleus contains genes (dna) and directs the manufacture of the proteins that run the cell, in cell body. Dendrites look similar to tree branches and receive information. Axons transmit information one neuron to the next (analogous to a telephone wire) Myelin sheath covers the axon to insulate it and make impulses travel along the axon faster and more efficiently. Axon terminal or synaptic terminal sends information across a synapse using neurotransmitters or electrical impulses. Sensory neurons sensory neurons detect information from the physical world and pass that information to the brain (e. g. , light receptor neurons in the eye or touch receptor neurons in the skin).
