The nervous system is a system in the human body that takes over all your thinking your movements and your balance and sensation. Your brain is an organ that’s in your head that has different parts. The nerve cells are your body is all over your body that helps travel messages. Lastly your spinal cord is a row of nerves that goes down your back.

[|Your brain] has different parts for different things like the cerebrum controls your thinking, speaking and breathing. Your spinal cord is a long row of nerves that help travel messages. The cerebellum controls your balance and sensation like when something is too hot you take your hand off right away. The brain stem is connected to your spinal cord. Lastly the thalamus is in the center of your brain and it thinks of the messages and sends it before you can even think of it.

The human body has trillions of nerve cells and your nerves are separated even in your face. Have you ever heard someone say, “It takes a lot of muscles to cry,” well there’s nerves in your muscles and your nerves tell your muscles to make you cry. The brain is where every thing starts like when you want to touch something your brain tells the nerves in your eyes to look at the thing you what then your brain tell the nerves in your legs to walk toward it then your brain tell the nerves in your had to grab it. The nervous system connects with a few of the other system in the human body like the muscular system connects with the nervous system because the nerve cells in your muscles help you lift weights when your in the gym, also when you want to pick up something heavy. With out nerve cells in your muscles you wouldn’t be able to pick up anything not even your pencil. Also the respiratory system connects with the nervous system because your brain tells your lungs to breathe.

Your brain is in your head under the skull witch is a hard piece of bone to protect head injuries. Also your nerves are all over your body, your legs, arms, feet everywhere. You name it there’s nerves there. Your spinal cord starts on the top of your neck to the bottom of your back and it’s a long row of nerves and it is very sensitive.

To keep your nervous system healthy you should avoid from falling backwards and that will lead to a concussion which means you hit your head very hard and you temporarily lose your memory. When you ride a bike, always were a helmet to protect your skull and also your brain.

All systems in the body are different but they have similarities one of them is diseases and injuries. The nervous system can get many diseases because it is sensitive. One of the diseases is when the immune system attacks the nervous system because it thinks it’s a foreign object. Also when people grow older the forget things that happened a short amount of time ago ; because their memory cells die, that means they have memory loss or disorder. Drugs, alcohol and smoking will kill your brain cells. When people have stroke it means that there brain is sending the wrong message and they can't move one or several parts of their body. My last diseases are becoming paralyzed; when you cut or crush your spinal cord you will become paralyzed (can't move their body for eternity and eventually you die).

All in all they are many diseases that can get to the nervous system. Also there are many organs in the nervous system. Wear a helmet when your riding your bike. Your brain has many parts for different things. The nervous system connects with circulatory and respiratory, but not just those, also digestive and reproductive and some others systems.
