The Hidden Story of Our Nose (Anatomy of the Nose): Let's Find Out!

We all think of our noses as just an organ for breathing and smelling, right? But our noses are actually a much more complex, important part of our bodies that performs many amazing functions. Just think about how uncomfortable we feel when our noses are blocked. So today we're going to talk about what's inside this nose, how it works, and the diseases that can affect the nose.

What is the nose? What are its parts?

Simply put, the nose is the main part of the respiratory system that protrudes from the center of our face. When viewed from the outside, it has the shape of a pyramid. The upper part that connects to the forehead is called the nasal root. The lower part where the nostrils are located is the apex. Okay, now let's look at the parts inside the nose. These are the parts that do the actual work of the nose.

What are the main functions of the nose?

The nose is a multifunctional organ in our body. It works in conjunction with organs like our ears and throat. That is why a sinus infection can also cause a sore throat. Let's talk about three main functions: 1. Respiration: This is the most important one. When we breathe, the air passes through the nasal cavities, it warms up to body temperature, adds moisture, and filters out dust particles and cleans them. Then it goes to the lungs. This means that the lungs get air that is not harmful to them and is suitable for them. 2. Defense Mechanism: The nose is like a guard in our body. Allergens in the air, such as dust, germs, and pollen, stick to the tiny hairs in the nose (cilia) and mucus membrane. This prevents these harmful substances from entering the lungs to a large extent. 3. Sense of Smell: The nose helps us to identify different smells. In medicine, this is called the ``Olfactory system''. Special nerves ``olfactory receptors'' located at the top of the nasal cavity detect odors and send that message to the brain. The brain interprets it as "this is the smell of flowers" or "this is the smell of a gas leak." This is why our sense of smell helps us avoid danger.

How do you recognize that there is a problem with your nose?

Like any organ, the nose can experience various problems. Some are normal, but there are some symptoms that we should be concerned about. Things like a common cold and a runny nose will go away in a few days. But you should be especially aware of the following symptoms. These could be signs of a more serious condition.

Common diseases affecting the nose

There are several medical conditions that affect the function of the nose.

• Deviated Septum : Some people may have a deviated septum, either from birth or due to an accident. This can cause breathing difficulties , snoring , and frequent sneezing.It could be a sinus infection. This may need to be corrected with surgery.
• Nasal Polyps: Small, painless growths inside the nose that can block the airways . This is more common in people who have frequent allergies or sinus infections.
• Turbinate Hypertrophy: Swelling of the turbinates inside the nose can also cause nasal congestion and difficulty breathing.
• Cancer: Although very rare, cancer of the nose (nasopharyngeal cancer) can occur. This starts in the upper part of the throat, behind the nose. It can cause difficulty breathing, speaking, or hearing.

How to maintain nasal health?

There are a few simple things we can do to keep our noses healthy.

• Don't pluck your nose hairs: These are essential for air filtration. Avoid cutting or plucking them.
• Drink plenty of water: Drinking enough water throughout the day helps keep your nasal passages moist.
• Avoid smoking: Smoking and inhaling secondhand smoke severely damage the mucous membrane of the nose.
• Keep your nose clean: You can keep your nose clean by gently using a saline water spray as directed by your doctor.
• Be careful if you have frequent nosebleeds: It's normal to have a nosebleed once or twice. But if this happens frequently, be sure to see your doctor to find out the cause.
