Nervous System ( ESSAY )

The nervous system is the system that processed and executed all your thoughts, actions, and your particular way of making a sandwich. It received stimuli from your skin, your eyes, your taste buds on your tongue and processed them so you can feel that it is a thorn you are holding in your hand, that the building you see are grey and cool looking, and that the food you are eating are very bitter. The nervous system are like the headquarters of your body. And like most of the stuff that is in science, it too is divided into subgroups, the central and peripheral nervous system. The job of the nervous system as a whole is : Sensory Input, Integration, and Motor Output. Let's talk about an example to further understand this three main jobs of the nervous system. Let's say that you are sunbathing on your big backyard, when suddenly a spider walk on your foot. The feeling you feel of those eight, tiny, little legs is the first of the three main jobs the nervous system do for you, the sensory input part. From there, the nervous system process that information, and then decide what should be done about it. That's the integration part. So if you do anything that you are ashamed of when your friend joke you by putting a fake spider on your lunchbox, you should blame your nervous system about it. Then, maybe your leg just shoot of and kick that spider halfway across the country, then you are in the third part of the nervous system's job, the motor output. It's commands your muscles to do something. So whatever little thing you do, thank the nervous system for it, and, most importantly, thank the Creator of such ingenious system. Now let's talk about the separate parts of the nervous system. The central nervous system consists of your brain and spinal cord, the main control center. The peripheral nervous system is, well the rest of the group, which is composed of all the nerves that branch of from the brain and spinal cord to the rest of your body and it's job is to bring the orders from your brain and spinal cord to your muscles, to do the order. And since it's job is for communication, the peripheral nervous system is set up to work in both direction, sending information to your brain, and also to receive the orders sent back by the brain. So that's the organization of your nervous system in a nutshell. If you want to know more about the individual parts of the nervous system, check out my next post - if it has been posted yet.
