In this essay I’m going to do my best to explain the nervous system. The Nervous System is broke into two categories: The Central Nervous System and the Peripheral Nervous System.
Nerves work sort of like electricity; and (I think) that the signals are sent a little bit like morse code. Different things send different intervals of electric signals through the nerves. The nerves are also responsible for all of the senses. Each of the sense organs (eyes, ears, tongue, nose, and skin) simply take their respective molecules, read them, and convert them into electrical pulses that run into the brain.
I’m going to start with the Peripheral Nervous System. The Peripheral Nervous system is divided into the Somatic and Autonomic Nervous Systems. The Somatic Nervous System controls thing in your body that you have to make a conscious decision to operate. If you are unconscious, these nerves basically stop responding. A good example of something controlled by the Somatic Nervous System is your fingers. The Autonomic Nervous System Controls the bodily functions that don’t take consciousness to try to operate. For example, if you are unconscious (maybe from a medication; it can be different if you’re injured), then your heart will still work without having to thing about it.
The Central Nervous System is the nerves that go down and around the spine. All the other nerves flow into the Central Nervous System which then moves the signals up to the brain.
