The nervous system is composed of the brain and spinal cord, together known as the central nervous system, and a vast array of peripheral nerves that transmit information to and from these central structures. The nervous system may be damaged by infection, injury, vascular problems, inflammation, and degeneration.
The ANS (Autonomic Nervous System) is a group of nerves that connect the major physiological control centres of the brain to practically all the bodyâs tissues and organs. The ANS can be separated into the sympathetic and parasympathetic nervous system. The Sympathetic nervous system is concerned with bodily mobilization and the expenditure of energy. It controls the commonly named âflight or fightâ response; that is, it prepares us for physical action to respond to emergency situations.
