What term defines the basic cell of the nervous system?

• A. Axon
• B. Neuron
• C. Dendrite
• D. Glial cell

Answer: (B)

The basic unit of the nervous system is the neuron. Neurons are specialized for rapid communication, using electrical impulses and chemical signals to relay information across the body. Dendrites are the branched inputs that receive signals from other neurons, the cell body integrates these inputs, and the axon is the long fiber that sends signals onward to other neurons or muscles. Glial cells, while essential for support, insulation, and nourishment, are not the primary signaling units and thus are not described as the basic cell of the nervous system.
