Illustration of upper respiratory system. In anatomy, a nasal concha ( / ˈkɒnkə /; pl.: conchae; / ˈkɒnkiː /; Latin for 'shell'), also called a nasal turbinate or turbinal, [1] [2] is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various other animals.
The inferior nasal concha ( inferior turbinated bone or inferior turbinal/turbinate) is one of the three paired nasal conchae in the nose. It extends horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone, curled upon itself like a scroll, ( turbinate meaning inverted cone). [1]
A CT scan showing evidence of the nasal cycle: the more patent airway is on the right of the image, the swollen turbinates congesting the left. The nasal cycle is the unconscious [1] [2] alternating partial congestion and decongestion of the nasal cavities in humans and other animals.
The nasal cavity is divided in two by the vertical nasal septum. On the side of each nasal cavity are three horizontal outgrowths called nasal conchae (singular "concha") or turbinates. These turbinates disrupt the airflow, directing air toward the olfactory epithelium on the surface of the turbinates and the 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.
Chronic atrophic rhinitis, or simply atrophic rhinitis, is a chronic inflammation of the nose characterised by atrophy of nasal mucosa, including the glands, turbinate bones and the nerve elements supplying the nose. Chronic atrophic rhinitis may be primary and secondary.
Concha bullosa. Concha bullosa on both sides (marked with asterisks), coronal orientated image from CT. A concha bullosa is a pneumatized (air-filled) cavity within a nasal concha, also known as a turbinate. [1] Bullosa refers to the air-filled cavity within the turbinate. [1] It is a normal anatomic variant seen in up to half the population.
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 ...
Empty nose syndrome ( ENS) is a clinical syndrome, the hallmark symptom of which is a sensation of suffocation despite a clear airway. This syndrome is often referred to as a form of secondary atrophic rhinitis. ENS is a potential complication of nasal turbinate surgery or injury. [1] [2] Patients have usually undergone a turbinectomy (removal ...
Middle nasal concha. Ethmoid bone from behind. Lateral wall of nasal cavity, showing ethmoid bone in position. (Middle nasal concha is at bottom of pink region.) The medial surface of the labyrinth of ethmoid consists of a thin lamella, which descends from the under surface of the cribriform plate, and ends below in a free, convoluted margin ...
