nerve cells are important because they transmit everthing to our brain. they use elelctric pulses a bit like Morse Code. without them we would not smell, hear,see,feel and move because the sending is a 2 way process. eg. your brain sends a message through the nerve's into the leg nerve and tells it to move and it does. the second is your organs to your brain. eg. nose send a signal to brain and message of the smell of your dinner and brain reacts and you start eating. in layment terms you could not do anything in the world except think to yourself.
