Neurons are fascinating cells responsible for transmitting signals throughout the body. Their two major functional properties, irritability and conductivity, allow them to respond to stimuli and quickly propagate electrical impulses. Think of irritability as a neuron's ability to "feel" when something is happening, while conductivity is like the "wires" transporting the message to other neurons or muscles at lightning speed! In the real world, these properties are crucial for everything from reflex actions (like pulling your hand away from a hot surface) to complex processes like thinking and learning. The rapid communication between neurons enables us to react swiftly to our environment and engage in higher cognitive functions that define much of the human experience.
