nasal concha, also called Turbinate, or Turbinal, any of several thin, scroll-shaped bony elements forming the upper chambers of the nasal cavities. They increase the surface area of these cavities, thus providing for rapid warming and humidification of air as it passes to the lungs.
What are conchae in anatomy?
In anatomy, a nasal concha (/ˈkɒnkə/), plural conchae (/ˈkɒnkiː/), also called a nasal turbinate or turbinal, is a long, narrow, curled shelf of bone that protrudes into the breathing passage of the nose in humans and various animals.
Where is the nasal conchae located?
The conchae are located laterally in the nasal cavity and covered by pseudostratified columnar, ciliated respiratory epithelium with a thick, vascular and erectile glandular tissue layer.
What causes nasal turbinate hypertrophy?
Allergies – Allergies can cause swelling, often leading to turbinate hypertrophy. Colds and Infections – Cold or infection may cause congestion due to enlarged turbinates. In most cases, the turbinates will return to their normal size after recovery.
What is the difference between meatus and conchae?
The superior meatus occupies the middle third of the nasal cavity’s lateral wall. The middle meatus is the middle-sized and located nasal opening, lying underneath the middle concha and above the inferior concha where the meatus extends along its length.
How many conchae are in the nasal cavity?
How many nasal turbinates are there? There are three nasal turbinate structures in the nasal passageway, but some people may have four. The first three includes the superior (upper), middle, and inferior (lower) turbinates.
Is concha and turbinate same?
[2][3] The bony components of the turbinates are referred to as conchae; the conchae of the middle, superior, and supreme turbinates are projections of the ethmoid bones, whereas the inferior turbinate – the largest turbinate – is a separate bone unto itself.
What is the function of the conchae in the nasal cavity quizlet?
The nasal conchae increases the cavity’s surface area and creates air turbulence to filter, warm or cool, and humidify the air.
Where are the nasal conchae quizlet?
~The superior, middle and inferior nasal conchae is where the nasal cavity ends and they form the lateral wall for each cavity. The inferior nasal conchae is the largest. The inferior, middle and superior meatus is the space below the conchae (ex: inferior meatus, inferior conchae, middle meatus, middle conchae, etc.).
What do swollen turbinates feel like?
If your lowest turbinates are swollen, you may feel congested and have difficulty breathing through the nose. If one or both of your upper turbinates are swollen (or being pushed on by the middle wall of the nose), you may experience a nasal headache – pressure beneath your eyes and pain in, around, or above your eyes.
What do enlarged turbinates feel like?
Someone who has turbinate hypertrophy can feel like they have a stuffy nose or trouble breathing all the time. A nasal steroid may decrease inflammation (and therefore, the swelling) of the turbinates, or surgery can be performed to decrease their size.
How do you fix swollen turbinates?
If your turbinates are swollen, your doctor may prescribe medication (e.g., nasal corticosteroid and nasal antihistamine sprays) to reduce the swelling. If enlarged inferior turbinates are causing your nasal obstruction, surgery may be the recommended treatment.
