On Monday, scientists announced the discovery of a brand new type of blood vessel in our bones.
As detailed in an article published in Metabolism of nature , the newly identified vessels cross the surface of the bones up to their interior. After all, the bones are also organs and have a blood circulation system that is reminiscent of our larger organs.
Researchers have dubbed the new vessels "trans-cortical vessels" because they pbad through the mouse all the hard and hard shell of the bone called corticalis.
"It is really unexpected to be able to find a new central anatomical structure that has not been described in any textbook in the 21st century," said co-author of the study, Matthias Gunzer, a professor at the University of California. University of Duisburg-Essen in Germany. A declaration.
Scientists first found evidence of TCV in the long bones of mice, they report in their study. Previously, scientists had identified only a handful of blood vessels entering and leaving the bones of mice. In mice, TCVs account for the majority of blood flowing through the long bones, the study said.
The researchers also found evidence of structures similar to those of TCV – although thicker than in mice – in small parts of the bones of human limbs.
According to the authors of the study, the discovery of the vessels is a "missing link in the search for a fully functioning closed circulatory system", which explains the circulation of blood in the bones.
Humans have sought to unravel the many mysteries of our own bodies for millennia, but our anatomy still has its secrets.
