Deviated nasal septum (DNS) An MRI image showing a congenitally deviated nasal septum, bowed to the left between the eye sockets. Specialty. Otorhinolaryngology. Nasal septum deviation is a physical disorder of the nose, involving a displacement of the nasal septum.
The human nose is the first organ of the respiratory system. It is also the principal organ in the olfactory system. The shape of the nose is determined by the nasal bones and the nasal cartilages, including the nasal septum, which separates the nostrils and divides the nasal cavity into two. The nose has an important function in breathing.
A perforated septum can vary in size and location, and is usually found deep inside the nose. It may be asymptomatic, or cause a variety of signs and symptoms. Small perforations can cause a whistling noise when breathing. Larger perforations usually have more severe symptoms. These can be a combination of crusting, blood discharge, difficulty ...
Uvula. The uvula ( pl.: uvulas or uvulae ), also known as the palatine uvula or staphyle, is a conic projection from the back edge of the middle of the soft palate, composed of connective tissue containing a number of racemose glands, and some muscular fibers. [1] [2] It also contains many serous glands, which produce thin saliva. [3]
Nostril. A nostril (or naris / ˈnɛərɪs /, pl.: nares / ˈnɛəriːz /) is either of the two orifices of the nose. They enable the entry and exit of air and other gasses through the nasal cavities. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove ...
This article describes the anatomy of the head and neck of the human body, including the brain, bones, muscles, blood vessels, nerves, glands, nose, mouth, teeth, tongue, and throat.
View of the larynx from behind. The epiglottis is the structure at the top of the image. The epiglottis ( pl.: epiglottises or epiglottides) is a leaf-shaped flap in the throat that prevents food and water from entering the trachea and the lungs. It stays open during breathing, allowing air into the larynx.
Frequency. ~7.5% of people in any 3-month period [5] Pharyngitis is inflammation of the back of the throat, known as the pharynx. [2] It typically results in a sore throat and fever. [2] Other symptoms may include a runny nose, cough, headache, difficulty swallowing, swollen lymph nodes, and a hoarse voice.
However, they are largest relative to the diameter of the throat in young children. In adults, each palatine tonsil normally measures up to 2.5 cm in length, 2.0 cm in width and 1.2 cm in thickness. The adenoid grows until the age of 5, starts to shrink at the age of 7 and becomes small in adulthood. [medical citation needed] Function
Adenoid. In anatomy, the pharyngeal tonsil, also known as the nasopharyngeal tonsil or adenoid, is the superior -most of the tonsils. It is a mass of lymphatic tissue located behind the nasal cavity, in the roof of the nasopharynx, where the nose blends into the throat. In children, it normally forms a soft mound in the roof and back wall of ...
