Scientific significance of the Nose

The best air filter in the world is the human nose. Your nose have tens of thousands of hairs that trap germs, viruses, dust and pollen.

There is a direct connection between your nose and your brain.

You don't smell with your nose. It is actually the mind that works. More than 10 million olfactory nerves in your nose pick up smells and send them to the brain. where the smell is then identified.

Your nose processes the air you breathe in, preparing it for your lungs and throat, which do not tolerate dry air well.

The framework of the nose consists of bone and cartilage. Two small nasal bones and an extension of the maxilla form the nasal bridge, which is a bony part. The rest of the framework is the cartilage and the elastic part. Connective tissue and skin cover this framework.

The partnership between your nose and sinuses helps control the amount of nitric oxide in your body and in your lungs. They also play a huge role in your immune function.

The sinuses are small, air-filled spaces behind your cheekbones and forehead. Mucus from your sinuses normally drains into your nose through small channels. In sinusitis, these channels become blocked as the sinus linings become inflamed.

The job of the sinuses is to warm and humidify the air you breathe in before it reaches your lungs. Breathing in warm, moist air is good for your health.

*    Your nose is attuned to your sense of taste. Just like when you have the flu, things taste different.

*    Your nose also indirectly affects your voice. Change of voice in cold or flu is a small example of it.

*    A recent survey in the Journal of Craniofacial Surgery identified 14 shapes of the human nose.

*    The human nose is capable of detecting more than 10,000 scents.

*    Your sneezing pattern may be genetic.

*    You don't sneeze in your sleep because the nerves that trigger sneezing are also asleep.

*    It's amazing that when a sneeze hits, it comes out at an incredible speed of 100 miles per hour!

*    A sneeze contains about 40,000 tiny moisture particles.

*    Because of the speed and force of a sneeze, germs from your nose fall up to 200 feet to the ground. So, for the sake of others, cover your face when you sneeze.

*    Light – especially from the sun – can trigger sneezing. That is why it is said to see the lights while sneezing.

*    The overall shape of your nose is formed by age 10, and your nose continues to grow slowly until about age 15 to 17 in women and 17 to 19 in men, Roerich says. But over time, the nose lengthens and droops due to the relentless tug of gravity and the gradual breakdown of the proteins collagen and elastin in your skin.

When you approach something smelly, the scent molecules enter your nose and wave over the olfactory sensors on the roof of your nasal cavity, where they activate finger-like receptors that transmit chemicals. do Your brain has a central processor called the olfactory bulb, which detects scents. This olfactory ability “plays an important role in the way we experience the world.

According to the University of Washington, humans have about 12 million olfactory receptor cells, a number that decreases with age. This is the reason why old people lose their sense of smell.

  Every day your nose produces 34 ounces or one liter of mucus. Fortunately, it doesn't come out of your nose too much. In fact, most of it goes down your throat. And it creates moisture there. In asthma, when the airways become dry, this fluid helps to moisten the airways.

Mucus contains chemicals that keep you healthy.

It's amazing that in a 24-hour period, 20,000 liters of air pass through your nose. That's the equivalent of 5,283 gallons. Best of all, this service is completely free.

According to neurological studies, humans are capable of recognizing a trillion different scents. Odor molecules bind to 12 million receptors in our nose to give us an incredible sense of smell.

Women have a 50% larger area of the brain for smell than men.¹

The sense of smell is the only one of the five senses that is directly connected to the part of the brain where memories are formed, and emotions are generated.³

Your inner nose is lined with microscopic hair-like structures, called cilia. Cilia deliver mucus to the back of the nose every five to eight minutes.

These cilia in the nose move up to 20 hours after death. Researchers believe that this can be used to measure the time of death.
