Compare And Contrast Nervous And Peripheral Nervous System

The nervous system is an important part of the human body. The system is made up of many different parts and each part is placed in either the central or peripheral nervous systems. These two parts work together and bring physical feelings and the proper reaction to them. The peripheral nervous system is the larger of the two systems. The peripheral nervous system consists of two more systems inside of it. The two other systems are the somatic and autonomic nervous systems. The somatic nervous system is part of a chain that helps you feel the world around you. The somatic nervous system consists of sensory and motor neurons all around the body. The neurons cover most of the human body and sends signals to the spine and brain so that the body can react accordingly to any sensations it might feel. For example: If a person was to step on hot sidewalk, the neurons would communicate to the brain and ask what to do and feel when stepping on the hot sidewalk. Neurons cannot think for themselves and need instructions from the brain, similar to
a child needing help from a parent. The other main part of the nervous system is the central nervous system.
The central nervous system is composed of the spinal cord and the brain. The spinal cord takes messages sent form the neurons and deliver them to the brain. The spinal cord is essentially like a mail man, or a phone to send a text message. The brain is the most important part of the human body and is very similar to a parent telling a child (in the case the neuron) what to do. The brain takes the messages given by the spinal cord from the neurons and figures out what needs to happen. Then the brain sends a message using the spinal cord to the neurons. In the example used before the neuron would send a message asking what the hot sidewalk feels like and what they should do to the spinal cord. Then the spinal cord would then send the message to the brain and the brain would figure out the sidewalk was hot and the neurons should feel hot and move off the
sidewalk. The nervous system dose this work in less than a second. All day long the system works so that the human body can feel and make respond accordingly. Without this system at work people would not be able to feel and would not last long in the world. Without this system people would have no feeling and would be unable to tell the dangers like fire, and extreme cold.
