Human body is hard to study and difficult to understand. Every organ is unique in itself. Also, even a single cell is so significant that it can destroy a human and even create one. The human body is full of amazing truths that a normal person does know about. Not everybody knows that the largest organ is skin which is about 20 sq. ft. Very few are aware of the fact that our nose can remember upto 50,000 scents. How of you know that if you avoid sleeping for 11 days, then you will die. There many other amazing unknown facts about this body. The following list definitely surprise you with these facts.
Mainly two groups of headaches exist: primary and secondary, which together include 200 types of headaches approx. Primary headaches are those where the problem causes headache like in case of migraine, tension, etc. Secondary headaches are those where headache is just a symptom of the problem like when you have a trauma or something else. Primary headaches can be treated by avoiding worrying about the cause of headache as it might worsen that. Secondary headaches are less common and can be treated by finding the cause of headaches and treat the same.
When the capillaries in our skin’s Dermis layer breaks, the blood flows in the interstitial space just below the epidermis. While kissing if someone sucks the skin, such a bleed occurs. This kind forms a bruise of the shape of your partner’s mouth. The size depends upon the strength applied while biting as well as the shape of the mouth.
8] “Eye Crusties” during sleep:
“Eye Crusties” is a kind of ‘rheum’, which is a substance discharged from eyes, mouth and nose while you sleep. This eye rheum or gound is a substance made from the mixture of dust, skin cells, blood cells, mucus (from conjunctiva), and an oily substance (from meibomian). When you are awake, the gound is washed away by the tears or when you blink. But during sleep, it collects at the corner of the eyes.
Friction blisters are nothing but result of excess friction. Our skin has three layers namely epidermis, dermis and subcutis. Epidermis itself has 3-4 layers. Repeated rubbing of the skin causes a split in the epidermis layers and the space is filled by plasma like fluid. If the skin is still under exposure to friction, the 3 layers of puss pocket will break which results in a leak of salty fluid.
6] Formation of scars:
Skin has a protein named Collagen made up of fibroblasts. After a scab, this fibroblasts leaks itself in the clot formed. After soaking completely, it releases Collagen which accelerates the growth which in return produces contractile proteins which forms scar. Scars do not have hair follicles, sweat glands or other protective gland.
5] One nostril at a time:
About 85 percentage of humans use one nostril to breathe. This process actually works in circular intervals of about 4 hours for each nostril. This also affects the brain activity. Studies show that breathing with a right nostril has more oxygen intake when compared to the left nostril. Also if you can control the nostrils, then you can control your brain’s activities.
All the varieties of birthmarks are caused by either pigment cells called Melanocytes or by blood vessels which accumulate at one skin area. If excess number of Pigment cells are present at some areas, then such birthmarks are known as ‘Pigmented Birthmarks’ and due to large no of cells on the skin, the combined colour creates an unusual skin which is visible as mark.
3] Voice speak during puberty
While a kid, our larynx is small. Just like a guitar in which the smallest and thinnest string has the highest pitch. As puberty arrives in boys, testosterone increases which increase the length and thickness of larynx which makes their tone of speaking much deeper. Though the voice of person also depends upon the nose, facial bones, throat-back, etc. the main cause is the thickness of the voice box.
2] Impossible to tickle yourself:
Human brain can differentiate between expected sensations and unexpected sensations. It generally diminishes or completely eliminates expected sensations. So there is no element of surprise if you are tickling yourself. All your movements and visuals are anticipated by the brain and it predicts the reaction. So the reaction is minimized or disappears. Whereas, on the other hand, when others tickle you, your brain is unknown of that fact and those unexpected sensations results in the tickling feeling.
1] ‘Tongue zones’? NO! ‘Tongue print’? YES!
As per a research conducted by Harvard Psychologist Edwin G. Boring, the ‘taste zones’ or ‘taste maps’ don’t exist. The German scientist who published about this got it wrong. There are actually taste buds on our tongue which are responsible for us to sense existing 5 types of tastes. Any undamaged taste bud can taste all the types of tastes and it depends upon the density of taste buds and their location on a person’s tongue. The locations of these vary from person to person. These variations in location of buds make Tongue Print of a person, which are unique for every person (just like the hand prints) and can be used to identify a person.
