You may get a “shock” when you see your mark on a test, or you may say you are “shocked” if you see an accident. But medically speaking, this isn’t shock. The word “shock” means a condition in which the essential activities of the body are affected. Usually, they are slowed up.

A person in a state of shock may nave a sudden or gradual feeling of weakness or faintness. He may become very pale, and the skin may feel cold and clammy. Perspiration is increased, and the pupils of the eyes become enlarged.
