Hey,

I've always imagined nerves as microscopic wires that are in our bodys, but how big are they and are they visible to the naked eye?

There are many types, just off the top of my head, they range from about 1 µm to 20 µm in diameter.

Actually, forget what I said, the smallest C-fibres are only about 0.2 µm
