Through thousands of years of research, scientists have clearlyhad to fully study the structure of the human body. But sometimes science gives us big surprises. It turns out that during the entire existence of mankind, in the center of the head of each of us there was an organ, the existence of which we did not even suspect. It is located deep inside the skull, closer to its base. Perhaps it is precisely because of its complex location that it has not been seen by doctors for many centuries. The discovery of a new organ happened unexpectedly, that is, researchers did not study the human body, hoping to find something new in it. The organ was seen during a scan of the body of one man. Before reporting their find, doctors clearly had to carefully study the new part of the human body. After all, who knows - maybe something is just stuck in the patient's head? But no, this is really an organ unknown to scientists.
New human organ
The unexpected discovery was told in the scientificjournal Radiotherapy and Oncology. A team of researchers from the Netherlands Cancer Institute studied a malignant tumor in the body of one of the patients. To do this, they used PET-CT technology. Substances were introduced into the man's body that can be absorbed by cancerous tumors. When saturated with this substance, a cancerous tumor becomes visible on the display of medical equipment. But sometimes this substance is absorbed by the real organs. During the study, scientists led by Professor Wouter Vogel noticed something strange on the screen.
What is saliva for?
The substance introduced into the human body wasabsorbed by the salivary glands. There are three of them in the human body: parotid, submandibular and sublingual. There are several more salivary glands inside the nasopharynx and digestive tract, but they are not considered large. They are visible only under a microscope and do not even form clusters. Their main function is to produce saliva. It is needed to moisten the mouth, improve taste perception, moisten food and make swallowing easier. It turns out that in the depths of the nasopharynx there is a fourth large gland.
More specifically, the new salivary gland is locatedbehind the so-called tube roll (Torus tubarius). The researchers named their find the tubarial. Like everyone else, this gland is needed to produce saliva. It is believed that this important part of the human body has remained unknown throughout history because it is hidden from view. But this is odd considering that doctors regularly perform surgeries. For thousands of years, they clearly must have discovered a gland that produces saliva, which is vital for the human body. Perhaps the doctors simply did not attach much importance to her.
To make sure it's not a mutation in the body of onehuman, scientists tested the presence of the gland in other people. In total, they checked about a hundred patients and a fourth salivary gland was found in each of them. In addition, the researchers opened the bodies of the deceased men and women - they also had a new salivary gland. Their tubal salivary glands were examined under a microscope. Scientists have found many tiny tubes in them, from which saliva is secreted. Researchers have suggested that the tubal salivary gland is essential for lubricating and protecting the nasopharynx.

Human body research
Finding new organs inside the human body is very rare. But such discoveries are made from time to time. In 2017, Irish scientists announced that mesentery, which is necessary for fixing internalorgans to the walls of the body, is a complete organ. They were convinced that the mesentery was needed not only for attaching the hollow organs to the back wall of the stomach. Scientists from all over the world are engaged in elucidation of other functions of the mesentery, but at the moment no one can give an exact list of its capabilities.

Few people know about this, but the salivary glands haveown diseases. More recently, I talked about how some people develop salivary stones that need to be removed through surgery. It sounds scary, but this is an interesting and very mysterious feature of our body. You can read more about this phenomenon in this article.
