Rare bone found in the hearts of chimpanzees, some chimpanzees have small bones in their hearts. A team of researchers in the United Kingdom discovered that some individuals of the common chimpanzee (pan troglodytes), particularly those affected by myocardial fibrosis, have a rare small bone called os cordis in their heart.

Cartilage (cartilago cordis) can also be present within the cardiac skeleton of individuals from other animal species such as horse, pig, dog, cat, rat, rat, snake, white rhino and Syrian hamster. Although the exact location, size, and number of the umbilical cord vary, in all species it occurs within a band of fibrous tissue called trigonum fibrosum.

Its function is unclear, but it is believed to serve as an axis and anchor support for the heart valves. The study’s lead author, Discovery of a new bone in the new species is a rare occurrence, especially in chimpanzees that have that anatomy for people, said Dr. Caterin Rutland.


A researcher at the University of Nottingham School of Veterinary and Science. This raises the question of whether some people may also have a cordis operating system. Dr. Rutland and colleagues compared the structure and morphology of 16 chimpanzee hearts that were healthy or affected by myocardial fibrosis, a type of heart disease found in chimpanzees and humans.

To study the organs, the researchers used a non-destructive X-ray imaging X-ray microtomography (Microtek) technique, which produces 3D images from 2D transaxial projections. They found the surrounding bone. A few millimeters in size, and the cartilage cordis in four hearts. Their presence was not associated with age.

There is a need to look for ways to help chimpanzees with heart disease, said first author of the Faculty of Veterinary Science and the University of Nottingham School of Science and Twicross Zoo.. Dr. Sophie Moitie said. Understanding what is going on in your heart helps us control your health. This research has brought together veterinary researchers and professionals.

Who are working on a common purpose to advance chimpanzee health and conservation, said Dr. Rutland said. Some chimpanzees have a bone in their hearts, and some humans, perhaps. Scientists in the United Kingdom have discovered a rare bone, called OS cordis, in chimpanzees with common heart conditions. The implications of this discovery may extend to humans, who share a close genetic connection with chimpanzees.


There are cows, buffaloes and sheep. So keep camels, camels, and dogs. Primates, not so much, at least what scientists thought. According to research published today in Scientific Reports, OS cordis is a small bone found in the hearts of some animals. This is the first time that Oss cordis has been detected in a large ape species. The rare bone structure was found primarily in chimpanzees suffering from idiopathic myocardial fibrosis (IMF).

In which the heart develops life-threatening scar tissue. The IMF is common in many animals, including chimpanzees and humans. Unexpected discoveries may lead to better treatment for the chimpanzee, a species for which heart disease is common. More research, led by the University of Nottingham School of Veterinary Medicine and Science, may also apply to humans, given the close relationship we have with the chimpanzee.

In a University of Nottingham press release, study co-author Caterin Rutland said: The discovery of a new bone in a new species is a rare occurrence, especially in chimpanzees, which is an anatomy for people. This raises the question of whether some people may also have a cordis operating system. For the new study, 16 chimpanzees, some with FMI and others without, had their hearts scanned with X-ray microcomputer tomography.

There is no need to kill animals, as all chimpanzees died of natural causes in zoos Europeans. The scan produced clear, high-resolution images that show small cordis from the operating system, measuring only a few millimeters wide. For anatomy there, this “hyperdense” bone structure was found within the right fibrous trigone. Simply put, this fleshy part of the heart forms a link between the aortic, mitral, and tricuspid valves.

rare bone structure

Some chimpanzees also exhibit cartilage cordis or cartilage formation in the heart. This is an important finding, since cartilage may have something to do with increasing rare bone structure, since cartilage has the ability to transform into bone. Three of our 16 chimpanzees had a cordis operating system and one had an Audi Cartilage, and all four were severely affected by the IMF, Rutland said in an email to Gizmodo.

The other 12 chimpanzees did not have an OS cordis or an OS cartilage but had low fibrosis levels or had no fibrosis. Therefore, we associate OB cordis with more severe fibrosis. Young and old chimpanzees, both male and female, may have os cordis, so that and age were not different, although older chimpanzees are generally more likely to have a more severe IMF.

physiological knowledge

As noted, the presence of Os cordis in chimpanzees raises the suspicion that it may also appear in humans under similar circumstances. As the authors point out in their study. However, it should be noted that not all chimpanzees affected by the IMF. So it may serve as an indicator rather than a diagnostic tool. The possibility of os cordis and cartilage cordis in humans suffering from similar cardiac disorders should be considered.

In conclusion of this new discovery, both OS cordis and cartilage cordis in the heart of the chimpanzee, highlighting the need for greater cardiac screening in this and other species, including humans using the latest technologies to obtain valuable clinical and physiological knowledge. It is worth noting that the correlation is not causal on the task.

bone structure

The link between the IMF and the OS cord has yet to be resolved and of course this strange bone has never been detected in humans, arguably the most studied animal on the planet. It would be a surprise to suddenly receive this rare bone structure in the human heart, but perhaps some scientists have overlooked it. Man has the ability to regenerate damaged body parts like “salamanders,” according to study results.

It is rare to find new parts of the human anatomy or previously unspecified physiological processes, but it happens. Recent examples include the lizard’s ability to recreate body parts like lizards. A new type of blood vessel in the bones, an organ in our skin that processes pain, and a salamander-like ability. This discovery is described in an article published in the journal Scientific Reports.
