Autonomic Nervous System
The autonomic nervous system is more of an internal system, connecting the central nervous system to the endocrine glands, the muscles controlling the heart, and the primarily involuntary smooth muscles controlling the other internal organs, such as the stomach, intestines, liver, and lungs. The autonomic nervous system is very important in emotion.
The autonomic nervous system is further divided into two branches: the sympathetic nervous system, which is more active in emergencies, and the parasympathetic nervous system, which is more active under normal circumstances.

The Brain
The brain has always attracted psychologists because its physiological activity governs most behaviors. Made up of billions of neurons, the human brain is more intricate than any computer. Most of the behaviors described earlier were controlled by the brain.

The spinal cord, housed in the spinal backbone, consists of bundles of nerves that form a communication link between the brain and the peripheral nervous system. One important function of the spinal cord is to serve as the pathway along which neural impulses from the sense organs travel up to the brain and other neural impulses from the brain travel down to the muscles and glands. Most of the peripheral nerves connect with the central nervous system through the spinal cord, and thus are called spinal nerves.

Our nervous system is divided into two parts: the peripheral nervous system, which receives messages from the sense organs and carries messages to the muscles and glands, and the central nervous system, which interprets and stress messages from the sense organs, decides what behaviors to exhibit, and sends appropriate messages for responding to the muscles and glands. Most of the behaviors involved in the above scenes are accomplished through the working of the central nervous system, which is composed of the brain and the spinal cord.
Thanks to the part of your brain that controls muscle coordination, the cerebellum, you are able to sit.

For information to get from one neuron to the next, it must cross the synapse, the space between the axon of one neuron (called the presynaptic neuron) and the dendrites of the next (called the postsynapstic neuron). The synapse is typically very tiny, about .03 microns wide or a millionth of an inch.
Unlike the electrical communication within a single neuron, communication between neurons involves a chemical reaction.

1. Fight free Radicals – Free radicals, small unstable oxygen molecules, attach to other cells of the body and break them down. The skin protein collagen is particularly susceptible to free radicals, which cause the collagen molecules to break down and re-link up a different way, which in turn makes them become stiff and less mobile.

1. Surgery: Crude, blunt and horribly painful
Surgery in the Middle Ages was crude and blunt and … PAINFUL! Surgeons had a very poor understanding of human anatomy, anesthetics and antiseptic techniques to keep wounds and incisions from infection.
