Scientists have discovered a new painful organ in the skin.
The cells form a network that detects painful stimuli such as bites and impacts.
Researchers at the Karolinska Institutet in Sweden say that this organ is sensitive to dangerous environmental irritation.
It consists of glial cells with long, long projections, which together form an organ resembling a mesh in the skin.
"Our study shows that sensitivity to pain does not only occur in the nerve fibers of the skin, but also in this newly discovered pain-sensitive organ," said Patrik Ernfors, the chief investigator of the disease. In a statement.
"Discovery alters our understanding of the cellular mechanisms of physical sensation and may be important in understanding chronic pain."
Published in the journal Science, the study describes the new organ sensitive to pain and explains how it is organized with nerves sensitive to skin pain.
The researchers say that the activation of the organ causes electrical impulses in the nervous system that result in reflex reactions and painful experience.
The organ is composed of cells very sensitive to mechanical stimuli, which explains how they can participate in detecting pin bites and painful pressure.
In experiments, the researchers also blocked the organ and found a decrease in the ability to feel mechanical pain.
Researchers say pain is a source of pain and costs society, but sensitivity to pain is also essential for survival and plays a protective role.
It causes reflex reactions that prevent tissue damage, such as moving away from your hand when you feel a blow from a sharp object or when you burn yourself.
