Neurons are the fundamental building blocks of the brain and nervous system, playing a crucial role in transmitting information throughout the body. Their primary function is to receive, process, and send electrical and chemical signals. Each neuron consists of three main parts: the cell body, dendrites, and axon.

Dendrites receive signals from other neurons, while the cell body processes this information. If the signal is strong enough, it triggers an action potential that travels down the axon, a long projection that transmits the signal to other neurons or muscles. At the axon terminals, neurotransmitters are released into the synapse, the gap between neurons, allowing communication to occur.

Neurons are involved in various functions, including sensory perception, motor control, and cognitive processes like learning and memory. They form complex networks that enable the brain to process vast amounts of information, respond to stimuli, and coordinate bodily functions. Overall, neurons are essential for maintaining the brain's intricate communication system, influencing behavior, emotions, and overall mental health.
