We are here today to talk about the nervous system. Something big just landed on my left arm. How does your brain know what your senses feel? And nerves are made of bonds of neurons. Specialized cells that carry message fast. Believe it and they don't even need a messenger bag. Most  nerves connect to the spinal cord and its mission The spinal cord zooms the message to your brain, which unpack the message and tries to explain. What it means and the brain controls your response. This message goes back spinal cord to nerve. Your arm moves and  you squash the bug in a blur. The central nervous System is the name. And the other nerve neurons and nerves in a different position.The peripheral nervous system. Abbreviated as CNS and PNS. Causing the four lines will leave me out of breath. Who's this with another neurons, spinal cord and brain. Control everything I think do and feel. The peripheral nervous system has two functions. So we can divide it into two parts, the somatic nervous system part. Runs on voluntary actions from the start, it turns into to your CNS. Then receives messages and makes your muscles flex .That's what happened with a bug before. There is a kind of environmental, there's a somatic controls. Here's what happens. If you touch a pan that is hot, a reflex takes place, it's shot. To your spinal cord through sensory neurons escapes your screen. So your refraction reactions is fast, that is a somatic system and its various task. There is another crucial part of the pns for most involuntary actions get down by the automatic nervous system is active. Even when you are still or asleep in my mattress. So your heart always beats and you always breathe. It's in charge when you cough and sneeze or when your pupils expand in the dark and to help you see chilling with the system. Controlling everything I think do and feel that's a nervous system, you know the deal.
