Definitions and how each part works
Dendrite: A short branched extension of a nerve cell, which impulses received from other cells at synapses are transmitted to the cell body.
Cell body: The nucleus-containing central part of a neuron exclusive of its axons and dendrites that is the major structural element of the gray matter of the brain and spinal cord.
Nucleus: The central and most important part of an object, movement, or group, forming the basis for its activity and growth.
Axon: Long threadlike part of a nerve cell along which impulses are conducted from the cell body to other cells.
Myelin Sheath: The insulating covering that surrounds an axon with multiple spiral layers of myelin, and that increases the speed at which a nerve impulse can travel along an axon.
Axon Terminals, (Terminal Buttons): The terminal Buttons of a neuron are the small knobs at the end of an axon that release chemicals called neurotransmitters.
Synapse: A junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
