The nervous system is made up of two parts which are then divided into several divisions, the central and the peripheral. As it goes deeper, the ring road is then also divided in two. The sensory division, which controls the senses, and the motor division, which controls how we move. The motor division is further separated into autonomic nervous and somatic nervous. The sympathetic is derived from the autonomic nervous system, which is responsible for the flight or fight response. Then the parasympathetic which is responsible for rest and digestion responses. The four characteristics of the nervous system are complexity, integration, adaptability and electrochemical transmission. The complexity of the nervous system allows you to integrate and carry out the multitude of basic tasks you do every day. These are the nerve cells in the brain that allow you to speak, write, think, and sing and dance. Integration is what brings information together, it integrates information into our systems. It gives us a fundamental sense of the things around us, like our senses themselves. What we hear, see, taste, smell and feel. Adaptability is just the ability of the brain and nervous system to adapt to our environment. The flight or fight response is also involved in adaptability. The last feature is electrochemical transmission, which is the work of chemical messengers, and impulses from the brain are sent to neurons. Say no to plagiarism.

I chose adaptability because of the four, it seems to be the least crucial part of the nervous system. There's no doubt that all four are important for the nervous system, but if I had to pick one to live without, it would be adaptability. Without complexity, you would not have the ability to speak, think, write or even sing and dance. Integration brings information into our system from our senses and I feel like it would further change my life as well. Electrochemical transmission is the basic messenger that sends signals from the brain to neurons to function. It’s also something we can imagine doing without. I feel like adaptability would obviously only affect the ability to adapt to my environment and my flight or fight response. The implications of the absence of this part of the nervous system would be my answer for survival. In addition to being able to change depending on my environment and certain situations. The flight or fight response is what causes the brain in a situation to react to an event, threat, or attack in order to survive. When I think about it, while it may be important, it rarely happens that I think I needed to wire my flight or fight backlash with my lifestyle. This may not be the case for other people. If there were a circumstance in which I needed to survive in a threatening event, I would be without coping skills, resulting in the loss of my flight or fight response. There would be no adrenaline created and I would not have maximum energy delivered to every cell in my body in hopes of surviving. All this is under the control of the sympathetic nervous system. This adaptation also speeds up your heart rate and increases your breathing rate in an attempt to make it out alive. Everything is changing around us and without the ability to adapt, I would be unable to adapt to the new environments and situations I find myself in..
