The nervous system is probably the most mysterious and complicated system in our body. Yet without it, none of the other systems could function optimally.
The central nervous system helps all the parts of the body, such as the digestive, endocrine, immune, lymphatic and muscular systems to communicate with each other.
Did you know that you have 43 different pairs of nerves that connect your central nervous system to the rest of your body, and that 12 of these nerve pairs connect to the brain, while the remaining ones connect with the spinal cord?
1) There are more nerve cells in the human brain than there are stars in the Milky Way.
2) If we lined up all the neurons in our body it would be around 965 km long.
3)There are 100 billion neurons in your brain alone.
4)A newborn baby's brain almost triples in size during the course of its first year.
5) 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.
6) A new born baby loses about half of their nerve cells before they are born.
7) There are about 13 500,00 neurons in the human spinal cord.
8) The nervous system can transmit nerve impulses as fast as 100 meters per second, and in some cases, the speed of transmission is around 180 miles per hour
9) Physical exercise increases the number of new nerve cells. Excessive stress and depression can decrease the growth of new nerve cells.
10) Scientific studies on neurogenesis reveal what many of us already knew. We can learn new things throughout life. A person in their eighties still grows new neurons but to harness the potential of these newborn cells, we need to keep challenging ourselves, explore new things, exercise, and see the proverbial cup, not as half empty, but as half full.
