Components of the neuron (pgs 79 80) Cajal discovered that neurons are composed of three basic parts: the cell body, the dendrites, and the axon. Cell body is the largest component of the neuron and coordinates functions such as protein synthesis, energy production, and metabolism to occur within it.
