All of us have felt pain, which can take complete control of our body and mind, making it impossible to move and even to think. Yet we need pain, without which we wouldn't know if we have hurt ourselves. It is our body's warning system, which tells us that we are injured and should do something about it.
Pain is the most common reason we go to a doctor or other healer. It is the most common reason we take medicine. Until recently, however, most doctors knew of only a few drugs that stopped some pains. They knew little about the process of pain itself, about which, however, new knowledge is helping them learn to control pain better.
Scientists have learned that the sense of pain is made up of both chemical and electrical signals, which travel from nerve cells (神經(jīng)細胞) in the injured area, up the central nervous system to the brain. And back down again. Scientists also have learned that the nervous system sends two different kinds of pain message to the brain, one very fast, and the other slow.
The first message is warning signal, which moves at a speed of 30 meters a second, and which travels to the middle part of the brain, and then to the outer part. In less than a second, the brain understands what part of our body is hurt and how badly it is injured. At a speed of only one meter a second moves the other message, which is the first step in the healing process, in which an important part is played by a very powerful material called prostaglandin, which are produced in almost every part of our body when needed. Scientists say prostaglandin raise and lower blood pressure, and also cause fever. When we hurt ourselves, the injured part produces a chemical that changes into prostaglandin, which cause the injured part to become red and swollen. and send the second, slower message of pain to the brain, which tells us not to use the injured part until it heals.
