Nasal concha
Nasal Concha
The Nasal Concha (pronounced: /ˈneɪzəl ˈkɒŋkə/), also known as turbinates, are long, narrow and curled bone shelves that protrude into the breathing passage of the nose. The term "concha" is derived from the Latin word for "shell", due to the structure's shell-like appearance.
Etymology
The term "Nasal Concha" originates from the Latin "concha", meaning "shell", and "nasus", meaning "nose". This is due to the shell-like structure of the concha within the nasal cavity.
Structure
The Nasal Concha is divided into three parts: the Superior Nasal Concha, the Middle Nasal Concha, and the Inferior Nasal Concha. Each concha is responsible for a specific function within the nasal cavity.
Superior Nasal Concha
The Superior Nasal Concha is the smallest and most superiorly located of the three conchae. It is involved in the process of olfaction, or the sense of smell.
Middle Nasal Concha
The Middle Nasal Concha is located between the superior and inferior conchae. It plays a role in directing airflow and conditioning the inhaled air.
Inferior Nasal Concha
The Inferior Nasal Concha is the largest and most inferiorly located of the three conchae. It is primarily responsible for filtering and humidifying the inhaled air.
Function
The primary function of the Nasal Concha is to increase the surface area of the nasal cavity, which aids in warming, humidifying, and filtering the inhaled air before it reaches the lungs. The conchae also play a role in the sense of smell.
