We all know that the body is a complex structure that is made up of many different parts and organs.
All body parts have their own functions and they contribute to the general functioning of the human body.
There are many body parts that start with the letter N.
In this article we are going to talk about them and we are going to explain you the most important information about each of them.
Most Common Body Parts That Start With N
Nose
The first part of the body that we are going to mention that starts with the letter N is the nose. As we all know, the nose is located on the face, that is, in the central part of the face.
It is undoubtedly one of the most important parts of the body. The nose together with the nasal cavity represents the initial part of the respiratory tract.
There are many different parts of the nose, such as the bone, hair and cilia, outer walls, nasal cavities, nostrils, septum, sinuses and turbinates.
The most important part of the nose are the sinuses and you have probably heard of them sometimes. It is important to know that we all have 4 pairs of sinuses.
The sinuses are actually the pockets that are filled with air and that are in relation with the nasal cavities.
The function of sinuses is to produce the substance called the mucus. This substance will keep your nose moist all the time.
The nose has a lot of functions in our bodies, but the most important of them is that the nose will allow the air to enter the body.
We breathe through the nose, more precisely the nose is only one of the organs belonging to the respiratory system.
The nose is covered with skin on the outside and it has left and right nostrils on the inside. The left and right nostrils are divided by a bone-cartilaginous structure.
The inside of the nostrils is covered with a mucous membrane on which there are tiny hairs. The function of those hairs is to retain microorganisms and dust that come from the air.
Also, this way the nose is filtering and cleaning the air, in order to remove all allergens and other bad substances from it.
The nose has also the function to warm and to moisten the air, so that the air can move into someone’s respiratory system without any problems.
Another function of the nose is that this organ provides us the sense of smell. Actually, the sense of smell is located in the upper part of the nose.
It is also interesting to know that the lacrimal-nasal canal flows into the nasal cavity.
The nose also plays an important role in speech because it enables resonance. The nose will determine how your voice will sound like.
Also, this part of the body can affect your physical appearance. There are many people who are not satisfied with their appearance because their noses don’t look good.
Some people have a big nose, while others have some kind of a hump or a bump on their nose.
Fortunately, today there are numerous cosmetic and surgical interventions that can quickly and easily bring the nose to a perfect appearance.
There are many conditions that can affect the nose. For example, we can mention allergic rhinitis. The typical symptoms of this condition are sneezing, irritation, stuffy and runny nose.
Other conditions related to the nose are deviated septum, nasal polyps, enlarged turbinates, infections, injuries, etc.
In order to keep your nose healthy, you should drink a lot of water every day and you should avoid smoking.
Also, it is important to maintain moisture at home. In order to do that you can simply use a humidifier.
You should never remove the hairs in your nose because they have the function to filter dirt and other harmful substances that you breathe in.
Another useful tip in order to keep your nose healthy is to avoid smoking.
Neck
The next body part that starts with the letter N is the neck. In anatomy, this body part is usually called collum or cervix.
However, you should know that the word cervix can refer not only to the neck, but also to the uterine cervix.
The neck is a part of the body that is located between the head and the torso.
Actually, this body parts serves as a connection between the head and the torso.
The anatomy of the neck is very complex. It contains many vital structures that enable us to breathe, to speak, to swallow, to regulate our metabolism, etc.
The function of the neck is to support the weight of your head and to protect the nerves that are going from the brain towards other parts of the body.
One of the most important properties of the neck is its flexibility. Due to the neck and its flexibility, we can turn the head and look in all directions.
It is also interesting to know that there are many muscles in the neck that attach mostly to the skull, but also to clavicles, hyoid bone, etc.
We have also to mention that common carotid arteries supply our neck with blood.
Neck pain is a common phenomenon, and it usually occurs due to improper position of the head or due to long sitting.
In addition, sometimes neck pain can indicate a more serious medical condition and we should take it seriously.
Navel
Another body part that starts with N is the navel. The navel is popularly called the belly button.
It is an organ typical for mammals. The navel is actually a scar that remains after the umbilical cord is removed.
The navel can have different shapes, so it can be concave, oval, round, vertical, etc.
The navel can also be sunken, bulging or completely flat. Different people have different navels.
In the past, showing the navel in public was considered vulgar, but today it is part of one’s outfit. Wearing short t-shirts and showing navels have become normal, especially among the younger population.
In addition, many people, especially girls, decide to have a navel piercing as a decorative item.
We will also mention belly dancing, which represents a type of dance that originates from Arab culture and in which the navel and torso play a major role.
It is interesting that in some cultures the navel is considered a source of special energy and has symbolic meanings.
Nail
There is another body part that starts with N and that is pretty small. It is the nail. The nail is a structure that protects the fingers and toes. Just like hair, nails are located in the middle layer of the skin.
The part of the nail that is embedded in the skin is called the nail root. The remaining part of the nail is the nail plate, which is colorless.
The transition between the nail plate and the nail root is called the lunula and has a semicircular shape. The lunula is visible in all people and it actually marks the beginning of the nail itself.
In cosmetics, nail treatments for women such as manicures, nail extension, etc. are extremely popular all over the world.
Also, it is interesting to mention that there are people who often bite their nails because of nervousness. That ugly habit has its own name and is called onimophagia.
Nipple
The nipple is the raised part of tissue in the center of the breast from which milk comes out so that the mother can nurse her newborn.
The nipple is surrounded by an areola that is generally darker than the rest of the skin. The anatomy of the breast in women is complex.
In women, nipples are erogenous zones and can be used for sexual stimulation.
We have already said that in women during breastfeeding, milk comes out of the nipples in order to feed the baby.
When mom breastfeeds her baby, there is a pressure on the breast and milk is automatically pumped out. This way the milk enters the baby’s mouth through the nipple.
However, sometimes it can happen that the nipples release milk for some time after breastfeeding, too.
But, sometimes fluid coming from the nipples can be a warning sign, especially if you notice blood coming out of the nipples.
In this case you should seek medical help as soon as possible.
