The ant’s brain is considered the largest among insects in relation to its size. It contains more than 250,000 neurons in the ant’s brain that is still unknown by scientists, and some researchers confirm that the ant’s brain works better than any computer in the world!
These nerve cells have a mission of sending messages, communicating and interacting.

There is a lot of information that we do not know about our bodies, including that there are organs in the body that blood does not reach directly, including the eye’s cornea. According to the “sciencefocus” website, it is one of the only living cells in the body that are not directly served by blood vessels but are accessed by oxygen and nutrients directly from the tear fluid outside and the aqueous mixture consisting of (the thick watery substance between the lens and the cornea) from the inside, as well as along the Nerve fibres attached to the cornea.
One of the problems with contact lenses is that they reduce the oxygen supply from the outside of the cornea, even with gas-permeable lenses, this can cause the corneal blood vessels to widen.
In addition to the cornea, there are other areas of the body that do not contain blood vessels, including “hair, nails, tooth enamel, and the outer layers of the skin.”

Did you know that the number of bacteria in the ear may increase by 700 times if the headphones are worn for an hour?
Using the earphone for long periods, such as leaving it all day, can cause many damages, including the pressure of earwax, making it more solid and challenging for the body to expel naturally, which may cause infections.
Among the disadvantages of these headphones, sweat and moisture trap in the ears, which makes them more susceptible to bacterial and fungal infections, and also creates a barrier to the natural expulsion of earwax, which eventually leads to the stimulation of the secretory glands and increased production and accumulation of earwax.

Did you know that human hair continues to grow for a few months after death?
When a person dies, their heart stops pumping the oxygen into the body, which is needed in the production of glucose, which the body, in turn, burns as hair and nails grow.
Since there is no energy supply to the body after death, hair and nails can’t continue to grow, but it lies in the reaction of the human body during the decomposition process, as after the passage of time, the water dries up in the skin, especially in the areas of the head and fingertips, which gives the impression that the hair and nails have elongated.

That when a person sneezes, all body systems, including the heart, stop for a few seconds.
Did you know?
A person cannot sneeze with his eyes open.
Sneezing occurs as the body tries to clean the nose. When foreign objects, such as smoke or dust, get stuck in them, the nose becomes irritated, causing sneezing. Therefore, sneezing is considered the first defensive stop for bacteria and insects.
Closing the eyes while sneezing is automatic, meaning you have very little control, and most people believe that sneezing while keeping their eyes open causes them to come out of their sockets, but this is widespread and unfounded myth.
Pressure from sneezing is unlikely to cause your eyeball to pop out even if your eyes are open. The increased pressure from stress builds up in the blood vessels, not in the eyes or the muscles around the eyes. This pressure in the blood vessels can lead to rupture of capillaries, which are the smallest vessels Blood in the body, which often appears in the eyeballs or the face.

That the tongue also has an imprint like a fingerprint?
The tongue is one of the largest muscles in the human body, but it has another uncommon benefit of having a special and unique fingerprint like fingerprints. The tongue is characterized by several characteristics that qualify it to be one of the ways to identify people, even if it has not been used yet.
The tongue is well protected inside the oral cavity and its imprint is difficult to falsify, and it can also be removed outside the body for diagnosis and examination. The tongue possesses two types of information that are not repeated or similar. The first relates to spatial information and the shape of the tongue, and the second relates to physiological texture. Another interesting piece of information is that bacteria in the human mouth – especially those located under the gums – are as powerful a component as fingerprints in identifying a person’s ethnicity.
