What is the basic unit of the nervous system?

• A. Axon
• B. Neuron
• C. Dendrite
• D. Synapse

Answer: (B)

The basic unit of the nervous system is the neuron. Neurons are specialized cells that transmit information throughout the body via electrical and chemical signals. They consist of a cell body, dendrites, and an axon. Dendrites are the branching extensions of neurons that receive signals from other neurons, while the axon is the long projection that transmits signals away from the cell body to other neurons or muscles. A synapse is the junction between two neurons where communication occurs, but it is not a unit in itself; rather, it is the connection point facilitating communication between neurons. Understanding neurons as the fundamental building blocks of the nervous system is crucial, as they play key roles in processing and transmitting information, coordinating reflexes, and contributing to all nervous system functions.
