Turbinates
Turbinates
Turbinates (pronunciation: /ˈtɜː.bɪ.neɪts/), also known as nasal conchae (pronunciation: /ˈneɪ.zəl ˈkɒŋ.ki/), are long, narrow, curled shelves of bone that protrude into the breathing passage of the nose. The term "turbinates" is derived from the Latin word 'turbinatus' (meaning shaped like a top) and the Greek word 'konkhē' (meaning shell).
Function
The primary function of the turbinates is to regulate airflow and increase the surface area of the nose, allowing for humidification, warming, and filtration of air before it reaches the lungs.
Types of Turbinates
There are three types of turbinates in the human nose:
- Superior Turbinate: The smallest and most superiorly located of the turbinates. It is involved in the sense of smell.
- Middle Turbinate: This is larger than the superior turbinate and plays a crucial role in the drainage of the paranasal sinuses.
- Inferior Turbinate: This is the largest of the turbinates and is primarily responsible for the warming, humidification, and filtration of inhaled air.
Related Terms
- Nasal Cavity: The space inside the nose where air passes on its way to the throat and lungs. The turbinates are located within this cavity.
- Rhinitis: Inflammation of the nasal mucous membrane, which can cause swelling of the turbinates.
- Turbinate Hypertrophy: A condition where the turbinates become enlarged, leading to nasal obstruction.
