Neuron

Imagine trying to send a message to a friend across a crowded room. Just like how you might pass the message along through a series of people until it reaches your friend, a neuron transmits nerve impulses through a network of cells to communicate within the nervous system. In this analogy, each person in the room acts like a neuron, passing the message (or impulse) from one to another, ensuring it travels successfully to its destination, much like how a neuron carries impulses to help the body respond to stimuli.
