What are facts about nerves?

Answer 1

Well. Nerves are quite amazing! I happened to be right in the middle of a project about nerves, so I'll share some of my research with ya ^_^

Remember your first time riding a bike without training wheels? It was probably really hard. This is because your nerves hadn't learned the pathway of motion (or the correct path to send messages through). When You finally DID ride your bike, you improved because your nerves had created a "muscle memory".

A nerve is a fiber that sends messages through your body telling certain things what to do. Lets say you're about to be hit. What do you do? You probably put out your arm in front of you in some sort of defense. Your nerves are telling you to do that, because they sense that something is about to happen.

Nerves are made up of TONS of Neurons. The fibrous part of your nerves (neurons) is covered by a fatty material called myelin. This is why messages are able to travel so quickly through your nerves.

At the end of the nerve, a synaptic terminal full of extremely tiny sacs which hold neurotransmitter chemicals transfers impulses from nerve to nerve, or from a nerve to a muscle cell. Electrical nerve impulses travel through the neurons, which then drop off the impulses in these sacs and release the chemicals. These chemicals find their way to a different neuron, which sparks an electrical charge that moves the nerve impulse forward. You'd think this takes about 2-3 minutes, but actually a neuron fires 500 times per second when they're "excited". Firing basically means to send out the neurotransmitter chemicals.

Hope this helped with whatever you were doing ^_^

Some interesting facts about nerves are:

1. nerves are also called Neurons.

2. nerves carry signals between parts of the body.

3. Our brain and the nerves together are faster then the fastest internet connection.

4. nerves control every action of our body.

5. Nerves use a complex process using chemical and electrical changes to carry messages.

Nerves carry messages between the brain and the different parts of the body . There are three kinds of nerves :

1 ) Motor nerves carry messages from the brain to the different parts of the body . 2 )Sensory nerves carry messages from the sense organs to brain.

3) Mixed nerves carry messages from brain to different parts of the body and from the different parts of the body to the brain .

Answer 3

There are more nerve cells in your body than the stars in the milky way!
