What are Conchae?

What are Conchae?

The conchae are structures made of bone inside of your nose. They help control the airflow into your nose. They also clean and warm air that you’ve inhaled so that it’s ready to go to your lungs for respiration. Respiration is the process of breathing in and out.

What are Conchae in anatomy?

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 bones make up the Conchae?

The three nasal conchae are curved bones that project from the lateral walls of the nasal cavity. The superior nasal concha and middle nasal concha are parts of the ethmoid bone. The inferior nasal concha is an independent bone of the skull.

What is the function of the inferior concha?

The inferior nasal concha is a scroll-shaped, paired bone that rests at the lateral wall of the nasal cavity. It helps to filter and humidify the air that we breathe. The nasal conchae (plural of concha) are also sometimes called turbinates.

What is another name for conchae?

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.

Are conchae the same as turbinates?

Turbinates are also called concha. Because the nasal cavity is symmetrical, there are technically pairs of turbinates, leading to 6 in total for an average human. These structures are on the lateral nasal wall.

Which bones make up the six nasal conchae?

Question 10 Which bones make up the six nasal conchae? ethmoid and sphenoid ethmoid has all six conchae inferior nasal conchae, ethmoid and sphenoid inferior nasal conchae.

Where is the inferior Conchae located?

nasal cavity
Inferior nasal conchae extend horizontally along the lateral walls of the nasal cavity, articulating with the medial wall of the maxillae and with the palatines. They also articulate with the ethmoid and lacrimals superiorly. The bones are rarely found isolated because they are so fragile.

Where are conchae located?

The conchae are located laterally in the nasal cavities, curling medially and downward into the nasal airway. Each pair is composed of one concha in either side of the nasal cavity, divided by the septum.

Where is the inferior conchae located?

What does the triangle mean in liver histology?

In this case, each functional unit is a triangle, having a central axis through a portal field and the imaginary vertices through the three different but closest portal canals surrounding it. The area covered by the triangle represents the hepatic regions that secrete bile into the same bile duct.

What is the pathological appearance of alcoholic liver disease?

The pathological appearance comprises microvesicular steatosis in virtually all hepatocytes, similar to that seen in diseases with mitochondrial dysfunction, such as Reye syndrome and fatty liver of pregnancy 1, 4 (Fig. 2 ). It usually occurs without histological steatohepatitis or steatofibrosis despite chronic alcohol ingestion.

What are the hepatic lobules of the liver?

• Hepatic Lobules: Structural units of Liver. Roughly hexagonal arrangement of irregular plates or cords of hepatocytes radiating outward from a central vein. 9. Concepts of Liver Lobules • Classical Hepatic Lobule • Portal Lobule • Hepatic Acinus of Rappaport

What kind of liver disease does micronodular Laennec have?

The progression of pericellular scarring to the end-stage liver disease of typical micronodular Laennec’s cirrhosis is complex (Fig. 6 ).
