The nose is an essential part of the respiratory system. Its function is to take air into the body, clean and heat the air before it comes into the lungs. In addition, the nose is also the organ of smell. The nose comprises three main parts: external nose, internal nose, and nasal cavity. Does your nose have a bone? This article will provide you with more knowledge of the basic structure of the human nose.
Main parts of nose
Main parts of nose consist of nostrils, septum, cartilage and nasal cavity.
In particular, nostrils are the two openings of the nose through which you breathe.
The septum lies between the nostrils and the nasal passages. Regarding structure, the nasal septum includes a bone – cartilage frame, specifically, in the front of the nose is septal cartilage, the ethmoid lies at the back of the upper frame, and the lower part is vomer. The mucosa covers the two sides of the bone – cartilage frame of the nasal septum. The length of the septum is from 7 to 8 centimeters, and the height is between 4 and 4.5 centimeters.
The nasal cavity is located in the nose. This part of the nose consists of the roof, the floor, the medial wall and the lateral wall. The nasal cavity and the mouth are separated by the roof of the mouth. It connects to the back of your throat.
Function of the nose
The nose has many uses. Below are three main functions of the nose:
- The nose is the head of the respiratory system.
- The nose must ensure that after going through the nose to the lungs, the air will be purified.
The nose will have to perform the specific works:
- Keep warm and moisten the inhaled air
- Filter, retain and excrete the harmful corpuscles and the stale air out of the inhaled air.
- Kill the microbe and the virus
- Absorb the moisture in the air
- The nose is also a sense of smell whose main function is to sniff.
- The nose is also involved in creating sounds. Previously, it was thought that the nasal cavity had the ability to support the resonance that made the voice deep, clear and continuing for a long time. But now, it is claimed that it has the function of producing nasal voices and absorbs the vibrations of the air when you pronounce.
Does your nose have a bone?
When pressing the upper third section of the root of the nose, you will find it firm and hard. This part is the nasal bone. If pressing any other places lying from the middle part of the bridge of the nose to the tip of the nose, you will feel that it is softer. The reason is that these parts are not bone. The lower third of the nose is cartilage. The cartilage is part of the framework on and around which are the cartilage organs. The cartilage is softer than the bone. The upper cartilage and the lower cartilage form the main part of the nose with the additional support of small cartilages with the less cartilaginous matter, which is called the accessory nasal cartilage.
All these cartilage organs form the nasal bridge. Because the cartilage belongs to the lower two-thirds part of the nose, this part is more flexible than that made of bone. It has an effect of protecting the nose from the risk of being broken. The lower cartilage combined with the adipose tissues and the associated organs curve to form the ala of the nose. With such a structure, it is effective in supporting the outer wall of the nostrils and keep your nostrils opening to take air easily.
As usual, the human nose is constituted of two nasal bones. Both of them lies in the upper part at the middle of the face. Nasal bones have a small size and the oblong shape, but the specific size and form will be different from person to person. The nasal bone together with the cartilage shape the nose.
Inside every nasal bone, there are four bones including two skull bones and two facial bones. Besides, the nasal bone consists of four borders, particularly, superior border, inferior border, lateral border and medial border.
Two surfaces of the nasal bone are the outer surface and the inner surface. The outer surface is an outward curve from side to side. At the center of the surface is a hole where a small vein is transmitted. Meanwhile, the inner surface is an inward curve moving between this side and the other one. Here there is a groove for the nasociliary nerve to go through.
Does nose bridge surgery affect the structure of the nasal bone?
As you know, the nose consists of two main parts: the inner and outer part. But regarding aesthetics, we only need to care about the outer part. The structure of the outer nose includes the skeleton, the cartilages, the muscles and the nose skin. The skeleton is the part that helps to form the basic shape of the nose. This shape is formed by the two nasal bones and nasal part of the frontal bone and the top of the forehead.
While the nose surgery, the impact on bone structure only occurs when the size of the nose is too large, so it is necessary to change it. In other words, whether raising the nose affects the bone structure or not, it depends on the state of the nose. If you own a nose with the slim figure and just desire to adjust the height of the nose, the cosmetic surgeon simply injects the filler into the defect areas or gently put the filler under the skin or on the nasal bone to raise the nasal bridge. In cases, the nose is too big, and the wing of the nose is wide open because of the broad bone structure, the adjustment of the bone structure is unavoidable so that the nose is taller and slender.
Nowadays, with the modern technique, the structure of the nose is almost not affected by severe results.
Hope that the article above helps you get the basic knowledge of the structure of the nose and the function of the nose as well as gives you the answer to the question “Does your nose have a bone?”. If you want to change the shape of the nose, you should consider this matter to avoid causing the nose to suffer from unexpected damage.
