In the world of science don’t happen every day opening that can really be a surprise to veteran researchers, but also far from scientific knowledge. Despite this, the team of Swedish scientists failed to detect in the human body is a special body, a discovery that could help expand our understanding of how we feel pain and how to relieve.
Why people can experience pain?
Perhaps you already know that we are able to perceive the full palette of sensations that occur with our skin due to a special particularly sensitive endings of our nerve cells. These cells are not covered to protect them a layer of myelin — a kind of shell, which, like duct tape, protects cells from damage. The absence of any of the coating distinguishes a nerve cell from another cell type. Despite this, all the nerve cells in our body live and have the ability to connect with other cells, called gleami. If glia are located outside the Central nervous system, these cells in science are called Schwann cells.
In an interview with Swedish researchers reported that during the experiment, which served as the basis for further scientific discoveries, they are faced with a special type of cells — cells are similar to Schwann, formed the extensive network of nerve cells in a different way than it had been earlier. When scientists conducted experiments on mice, it was discovered that these Schwann cells directly responsible for our perception of pain and irritation. The new cells were proposed to be called nociceptive or pain receptors. The nociceptors are the mediators between the spinal cord and the brain, allowing the living being to experience pain is necessary for the evolution of the body.
One of the experiments conducted by Swedish researchers, involved the breeding of mice with such little-studied cells in the legs, which could be activated when mice were exposed to the light. Once turned off the light, the mouseseemed to behave as if they were in pain while licking himself or protecting his paws.
Due to the fact that these cells are distributed throughout the skin in the form of complicated coupled system, the authors argue that this cluster of cells should be considered as a single body. In other words, sensitivity to pain can occur not only in the nerve fibers of the skin, but in the newly discovered parts of the body.
