What role do neurons play in the nervous system?

Neurons are specialized cells that play a crucial role in the nervous system by conducting nerve impulses. This function is fundamental to the way the nervous system operates, facilitating communication between different parts of the body. Neurons transmit signals through electrical impulses, allowing for rapid response to stimuli, coordination of bodily functions, and processing of sensory information.

In understanding this role, it's important to note that while other cells in the body are involved in various functions such as regulating heart function, producing blood cells, or supporting muscle contractions, these activities are not the primary function of neurons. Instead, neurons are the key players in transmitting signals that enable the nervous system to function effectively, thereby controlling everything from reflexes to complex processes like thinking and decision-making.
