The nervous system is literally the nerve center of all the other systems. The nervous system comprises the brain, spinal cord, nerves and neurons (nerve cells).
One of the key responsibilities of the nervous system is to regulate immune function. Nerve fibers lead from the brain stem and spinal cord to the thymus, where immune cells receive specialized training. Neural pathways connect the brain to the immune system, and the mind coordinates immune function through chemical and electrical signals. Through these channels, the nervous system has the power to spur immune cells into action when the body is under attack. This same process orders the immune cells to stop fighting once the infection is defeated.
The brain's influence on immune function can also be psychologial. Studies show that having a cheerful mindset can reduce visits to the doctor by 50%. Indicating that the immune system of people who think positive is stronger. In the same way, a negative approach to life has been shown to interfere with immune function.
