Definition: A bundle of neurons with their connective tissue sheaths, blood vessels and lymphatics.

Alright class, settle down, let’s take a look! That dictionary definition – quite a mouthful, isn’t it? It tells us exactly what ‘nerve’ is made of, but sometimes we need to understand it in a simpler way. Let's break it down like this: "Nerve" really means our body’s speedy messengers! Think of it as a wire, but one that carries signals incredibly fast. Neurons: These are the tiny building blocks – little cells that send messages. They’re like individual postmen delivering letters. Connective tissue sheaths: These are like protective tubes around each neuron, keeping them safe and helping them travel smoothly - like wrapping a wire to keep it neat! Blood vessels & lymphatics: These bring the nutrients and oxygen that the nerves need to work properly, just like delivering fuel to a busy train station. So, when you feel a tingle, or a sharp pain, or even a warm sensation, it’s all thanks to these amazing nerve bundles doing their job! In short: A nerve is a network of cells that transmits information throughout your body – letting you think, move, and feel ! Do you have any questions about this? Don't be shy - let's explore it together.
