2.The shape of nose depends on the ethnic background of a person.
Positions of lower and upper lateral cartilages and nasal bones actually define nose shape.
3. Different people have different sneezing styles and these styles are
genetically determined. So, the members of a given family will have
similar sneezing styles which will be different than the sneezing styles
of other families.
4.. During sneezing, irritants (that cause sneezing) are expelled at a speed of 100 miles per hour.
5. In women, nose grows until the age of 15 to 17 and for men, it is 17 to 19.
6.
Nose droops and lengthens over time because of gravitational pull. This
happens because elastin and collagen in nasal tip breaks.
7.
The best air filter in this world is human nose. Human nostrils are
lined up with hair responsible for blocking germs and dust. Grooves in
nasal cavity make air swirl like stream currents. This is when the
inhaled hair is moistened and warmed so that the sensitive tissues of
the lungs can be protected. It is during this filtration process that
the mucus lining of the nasal cavity captures cold viruses and pollen
which cannot be stopped by hair in nostrils.
8.
Mucus is produced by human sinuses and nose and it contains white blood
cells and enzymes responsible for fighting infections. One quart mucus
is produced daily.
9.
When someone inhales dry air, the air picks up moisture content from
mucus. This makes the mucus pasty, which is known as snot or boogers.
10. When
a person becomes sick because of flu, the nose becomes runny. This
happens because the nose produces more mucus than usual in an attempt to
kill microbes invading the body. Humans are capable of detecting 10,000+ scents. Humans can detect smell
with special types of cells known as olfactory nerve cells. There are
nearly 12 million olfactory cells present in a normal human. However,
this number gradually decreases with age.
11.
Olfactory nerves from nose have direct connection with brain. It is
because of this that several types of smells can bring memories back.
12.
Sense of smell is the only one of the 5 senses in humans which has
direct connection with hippocampus – the part of the brain responsible
for formation of memory.
Humans release pheromones – a type of chemical released only in
response to sexual attraction. Nasal grooves in nostrils are sites rich
in pheromones. Human nose is capable of detecting pheromones of opposite
sex. According to experts, it is the pheromones in nose that led to the
birth of smooching or romantic kissing.
13.
Anything that human nose cannot smell is lethal to humans. For example,
human nose cannot smell natural gas (one that humans can smell is
actually a different compound called mercaptan added to natural gas),
carbon monoxide, carbon dioxide etc.
14.
Humans don't smell with nose. It is the brain that does the job. The
olfactory nerve cells in nose are only responsible for capturing smell
and sending them to the brain. It is the brain where the smell gets
identified.
Interesting! Lol@ do you have a nose.
