The Sense Of Touch Protects The Body

People might not notice this but our sense of touch plays an important role in protecting our body from harm. Without such sense, we could easily injure ourselves. Your skin continuously passes huge amounts of information to the brain. It monitors touch, pain, temperature and other factors that tell the brain exactly how the body is being affected by the environment.

Without this constant flow of information, you would keep injuring yourself accidentally. This is what usually happens to people who have this rare disease wherein the skin senses are lost.

Sensations in the skin are measured by tiny receptors at the ends of the nerve fibers. There are several different types of receptors. Each type can detect only one kind of sensation such as pain, temperature, pressure, touch and so on.

Without such receptors our body cannot detect the different factors in the environment and are therefore prone to accidents and injuries.

This is also the reason that some pain can be taken out by taking in pain killing drugs. Basically pain killing drugs or analgesic work in two different ways. Some drugs such as aspirin work by preventing the sensation of pain from reaching the brain. More powerful pain killing drugs prevent the brain from reacting to the nerve impulses that it receives from the pain receptors.

It is just amazing how our system works. It is simple yet very complex. Truly our body is a great machine that is very hard to replicate. No machine has ever been made that is as complete and marvelous as a human being.
