The Neuron
The neuron, the basic building block of the nervous system, has three main components: (1) the cell body, which contains vital cellular structures; (2) bushy dendrites that receive messages from neighboring neurons; and (3) a long, thin axon that sends messages to other neurons through its branchlike terminal buds.
