The nervous system is a complex network of nerves, impulse pathways, the spinal cord and brain. It is the system in the human body that is responsible for sending, receiving and interpreting stimulation from the surrounding world. It is made up of three main sections, the central nervous system which is comprised of the spinal cord and the brain, the peripheral nervous system which is made up of the nerves and impulse pathways and the autonomic nervous system which is made up of the sympathetic and parasympathetic systems.
What is the function of the Nervous System?
The primary function of the nervous system is to send and receive signals as well as interpreting the stimulation received from the surrounding world. The central nervous system is responsible for sending signals to the other parts of the body to allow them to function correctly. It is also responsible for interpreting the signals it receives from the nerves and sensory organs of the body. The central nervous system allows you to understand when something is causing you pain or to interpret the speech you are hearing. The peripheral nervous system carries the signals or nerve impulses sent from the brain to the different parts of the body. It also gathers sensory data to send back to the brain. The peripheral nervous system includes such body parts are your eyes, ears, nose and hands. The autonomic nervous system is responsible for regulating and coordinating the functions of the vital organs within the body. It is this system that allows your heart to beat regularly without conscious thought and for you to breathe even while you sleep.
