Human Nervous System - Essay Example The central nervous system (CNS) of the body is basically responsible for all the unintentional and reflex nerve action. It basically means that the central nervous system takes care of all the nerve action meaning that any type of nerve reaction is the sole responsibility of the CNS (Standley, 2013). The central nervous system (CNS) has the responsibility for almost all thing that a human being does. From the simple act of breathing to the complex mental abilities that help solve complicated mathematic problems are all the direct responsibility of the Central Nervous System (CNS) (Buzzle.com, 2013). Perhaps the simplest example of what the Central Nervous system does is in the fact that as soon as someone’s hand touches a hot object, the body reacts within milliseconds and the bodies reflex is to draw back the hand immediately. Behind this simple activity are sensory tasks performed by the Central Nervous System whereby the hot sensation registered by the hand is transmitted to the brain, is decoded by the brain and the brain instructs the specific part to perform the action of drawing back the hand. All this activity is undertaken in less than a whole second and the Central Nervous System (CNS) is responsible for it. The Autonomic Nervous System (ANS) (Dorland's Medical Dictionary, n.d.) is also known as the visceral nervous system or also the involuntary nervous system. Autonomic Nervous System (ANS) is a part of the body’s peripheral nervous system(PNS) and acts as a control system.
