The nasopharynx is the uppermost part of the pharynx and extends down from the base of the skull to the nasal passages, hence the name.

  4. The nose has two cavities, separated from one another by a wall of cartilage called the septum. The external openings are known as nares or nostrils. The roof of the mouth and the floor of the nose are formed by the palatine bone, the mouth part of which is commonly called the hard palate; a flap of tissue, the soft palate, extends back into the nasopharynx, the nasal portion of the throat.
  5. The nose is one of the essential sense organs of the body and is required for smelling and breathing. It is the only visible part of your respiratory system and consists of mucus and cilia (hair-like structures) that filter out foreign particles from entering your body or lungs.. When we breathe, the air enters our nostrils, travels through our throat, and finally enters the lungs
  6. The nose is made up of: External meatus. Triangular-shaped projection in the center of the face. External nostrils. Two chambers divided by the septum. Septum.

Nose. The external nasal anatomy is quite simple. It is a pyramidal structure, with its root located superiorly and apex sitting inferiorly.The root is continuous with the anterior surface of the head and the part between the root and the apex is called the dorsum of the nose. Inferior to the apex are the two nares (nostrils), which are the openings to the nasal cavity The nose from a side profile (A) is always protruded outwards so when looking down, the nose tip should also go down and when sectioning the face vertically into 3, it shouldn't be sectioned into the nose tip, but the sides of the nose (B) instead (see diagram) Lateral wall of the nasal cavity. The lateral wall of the nasal cavity is a region of the nasopharynx essential for humidifying and filtering the air we breathe in nasally. Here we can find a structure called agger nasi. The agger nasi is also referred to as the 'nasoturbinal concha' or 'nasal ridge.'

The inside of the nose, including the bones, cartilage and other tissue, blood vessels and nerves, all the way back posteriorly to the nasopharynx, is called the nasal cavity. It is considered part of the upper respiratory tract due to its involvement in both inspiration and exhalation The nose is divided into two parts, the visible part called the anterior and the back part called the posterior. The back, or inside part of the nose leads directly into the throat. The throat is comprised of three parts; the nasopharynx, located behind the nose, the oropharynx behind the mouth, and the laryngopharynx where the voice box is housed The structure of nose is explained as follows: Bone: It supports the bridge of the nose. Cartilage: The upper cartilage provides support to the sides of the nose. The lower cartilage adds width and height to the nose. It provides shape to the nostrils and nose tip. Nasal Cavity: It is the hollow space through which the air flows If you have trouble breathing out of your nose or experience frequent sinus pain, you may need a CT scan to determine if a sinus blockage is the cause of your symptoms.

Nasal congestion is a blocked, stuffy or bunged-up feeling in your nose. Depending on the cause, it can last a short while (a few days) or can be persistent. In adults and children it is usually an annoying symptom rather than a serious one.

You can imagine what might occur if there is a septal deviation on top of all this. If the septum is deviated and already causing some degree of nasal obstruction, the turbinate hypertrophy will just compound this problem Update 09-26-2012 - Above is a video version of this tutorial.

Nose and nasal cavity are divided into two halves by the nasal septum. The lateral wall of the nose consists of three turbinates or conchae (superior, middle and inferior). The passage inferior to inferior turbinate is preferred passage for nasotracheal intubation. The pharynx is a tube-like passage that connects the posterior nasal and oral. Pharynx carries air from the nose and mouth toward the larynx. Inflamed adenoids or tonsils, sudden swelling from an insect bite or allergic reaction, stuck food or detached dentures, or injury of the pharynx can all impede breathing. 3. Speech.
