Question

Hi:)
I need fun facts about the nervous system, fun or interesting facts :)
(2-3 facts)

Answer 1

Here are 10 fun facts about your nervous system:

- There are more nerve cells in the human brain than there are stars in our galaxy.

- If we lined up all the neurons in our body it would be about 965km long.

- There are about 100 billion neurons just in your brain.

- A baby’s brain grows almost three times its size in the first year.

- The left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body.

- A newborn baby loses about half of their nerve cells before they are born.

- The nervous system can transmit information across nerves as fast as 360km/h.

- A man’s brain has 6,5 times more grey matter compared to women, but a woman’s brain has 10 times more white matter compared to men.

- There are over 200 different kinds of nerve cells in the average body.

- Your nervous system cannot function properly in the absence of potassium and sodium. Vitamin B is equally necessary for your nervous system.

Answer 2

Here are 11 Fun Facts on the Nervous System which I found interesting.

1. The basic unit of the nervous system is the neuron. These specialized cells have a cell body or soma, axons, and dendrites.
2. The brain uses more of the body’s energy than the rest of the organs, using over 20% of the energy reserves in the body.
3. The brain is hard at work even when you’re sleeping.
4. The brain’s structure is constantly changing as we learn. New neuronal connections are made which increases the density of the brain.
5. Some neurons have an insulating layer known as the myelin sheath. This allows nervous impulses to travel faster, with less energy lost.
6. Involuntary reflexes are not controlled by your brain. They are controlled by a reflex arc.
7. The fastest signal transmission in the body occurs in the alpha motor neurons within the spinal cord. They transmit a signal at 268 miles per hour. The slowest signal transmission is within the skin at 1 mile per hour.
8. Neurons can’t divide or replace themselves. This means that nerve damage is often permanent.
9. We lose neurons as we age, starting at around 20 years old in humans. 1/10 of our neurons are gone by the time we turn 75.
10. Electrical impulses within the nervous system are triggered by ions or chemical signals that pass through channels in the neuron.
11. Ions that are important in chemical signaling include sodium, potassium, chloride, and calcium.
