The Anatomy of the Nose

By Edited Nov 13, 2013 0 0

The nose is a very significant part of the body and is responsible for the sense of smell. Aside from its main function when it comes to smell, the nose is also very important in filtering the air and ensuring that it has proper temperature before it is allowed to enter the lungs.  The nose is greatly visible on the face but it also has underlying parts that have several important functions as well. We can actually divide the nose into two areas which are the internal and the external parts. The external part is the one that is clearly visible while the internal part is the one located deeper in the nose.  The nose is made up of different structures like blood vessels, nerves, bone, cartilage, and skin. These parts work all together to be able to play significant roles for the body’s normal functioning.

The External Parts of the Nose

The Dorsum

The dorsum is also known as the nasal bridge which marks the contour or the primary shape of the nose.  It is described as a soft slightly curved line that starts from the area near the eyebrows up to a significant point above the upper lip. The characteristic of the dorsum actually differs for every person. The dorsum can significantly define the shape of the nose as either flat, big, wide, or just right.

The Nasal Tip

The nasal tip or the apex  is considered as the highest point of the dorsum or the nasal bridge  and also has several characteristics which widely differs for every person. Some may have a large nasal tip while others may simply have a small one.

The Nostrils

The nostrils or the nares are known as the holes of the nose. The nostrils serve as the entrance and exit of any substance that may go in and out of the nose. This is where air is primarily inhaled into and exhaled out of the body.

The Columella

The columella is known as the division of the nostrils and is described as a small piece of skin just below the tip of the nose.

The Internal Parts of the Nose

The Nasal Cavity

The nasal cavity is known as the tunnel like area which serves as a passageway of air, mucous and other substances that move in and out of the nose. It is separated into the left and right parts by the nasal septum. The nasal cavity is actually covered with a membrane known as the mucous membrane. This membrane serves to warm up the air that enters the nose. It also serves to add up moisture to the air so that it can effectively pass inside the body. The nasal cavity has a protective function for the body through its mucous membrane. The mucous membrane secretes a thick and sticky substance known as the mucous which serves to trap all the dust, dirt and any other kind of unwanted particle that may pass through your nose and eventually affect the organs inside your body primarily the lungs

The Cilia

The cilia are known as the tiny hair-like structures that are lined up in the nasal cavity. Cilia plays a very important role because it serves to filter and air and promotes the effective movement of mucous out of the nose for removal.

The Nasal Septum

The nasal septum is described as a cartilaginous and bony separation or divider of the nose into the left and right parts. It is described to be a thin wall that can be found at the central part of the nose.

The Sinuses

The sinuses are very essential parts of the skull which serve to provide much needed resonance to voice. Sinuses are described as hollow areas within the bones that are lined with mucosa. Being lined with mucosa, the sinuses serve to filter the air that passes through the nose together with providing it with the appropriate temperature and humidity needed before it could finally go to the lungs. There are four different pairs of sinuses which are the ethmoid sinuses, frontal sinuses, maxillary sinuses and sphenoid sinuses. Each of these sinuses are distributed at different specific portions on the face where they are all connected to the ostia  or small tubes that are directed towards the nasal passages.

These are just some of the most important parts of the nose that work together to achieve proper hearing. Care must be appropriately given to all of these parts so that they could be able to maintain their normal function.

Common Nose Problems

There are a lot of common nose problems people should definitely be aware of. Knowing all of these well-known nose problems can definitely help people understand the best treatment methods  to help them get rid of such medical conditions. The following is a list of these conditions:

Common Cold

One of the most common nose problems that can affect anyone regardless of age is the common cold. The common cold is a type of infection that is specifically caused by a virus.  It  is also known as viral rhinitis and is associated with symptoms like sneezing, runny nose and nasal congestion. Aside from these, some of the medical conditions that can normally go together with a common cold are cough, sore throat, headache and  sometimes fever, especially in the presence of an underlying infection.

Common colds can be easily treated and most people should know that you do not initially need to take medications for it. You can simply try to increase your fluid intake, take vitamin C and ensure that you have proper rest to try to relieve its symptoms. When the symptoms persist after using such methods, then you can try to use antiviral medications to effectively treat a common cold.

Choanal Atresia

Another one of the better known nose problems that can be experienced by anyone is Choanal Atresia. Choanal Atresia is actually known as a medical defect that greatly affects newborns. This condition is described as the blockage or narrowing of the nasal passage.

Some of the most common symptoms associated with Choanal Atresia are difficulty in breathing together with a change in the color of the skin, lips and even fingernails to a bluish shade due to an observable lack of oxygen.

Aside from these, chest retractions can also be observed for those who are diagnosed to have Choanal Atresia.  This nose problem can be effectively treated by intubation, tracheostomy and sometimes a surgical procedure that permanently creates an airway.

Hay Fever

Hay Fever can also be considered as one of the most common nose problems encountered by people. If common cold is known as viral rhinitis, Hay Fever is actually known as allergic rhinitis. Some of the symptoms associated with this nose problem are sneezing, runny nose and nasal congestion together with a very uncomfortable feeling of having a reduced sense of taste and smell.  

Aside from these, cough may also be frequently experienced by people diagnosed to have Hay Fever.  People with Hay Fever also experience pain in the face, primarily in the nasal area together with swelling of the eyes and weakness. 

These are just some of the most common nose problems that can be experienced by anyone. All the details about the Hay Fever, Choanal Atresia and the Common Cold, including the causes, symptoms and the treatment methods should be made aware to the people so that they can be prepared enough to face these issues if they encounter them.
