Document Summary

Basic building blocks of the nervous system. Transmit messages throughout the brain and between the brain and the rest of the body. Hollow tube that conducts signals; carries action potentials. Provide physical and functional support for neurons. Create matrix to hold neural cells together. Convert glucose to lactate for neuron"s use. Fatty, insulating layer covering axons, speeding neural signals. Immune cells produce too much glutamate, which damages/ kills myelin producing glial cells. When myelin breaks down, neural signals slow/ stop. Carry informations from the central nervous system (cns) to destinations outside of the brain (muscles, glands) Have signals exiting the central nervous system. Take information from sense receptors to the central nervous system. Have signals that arrive at the central nervous system. Peripheral nervous system made up completely of efferent and afferent neurons. Central nervous system made up of interneurons. About 99% of neurons in the nervous system are interneurons.
