Alar cartilage
Alar Cartilage
Alar cartilage (pronunciation: /ˈælər kɑːrˈtɪlɪdʒ/) is a significant component of the nasal anatomy that contributes to the shape and flexibility of the nose.
Etymology
The term "alar" is derived from the Latin word "ala," meaning "wing," and "cartilage" comes from the Latin "cartilago," referring to gristle or hard tissue. Thus, "alar cartilage" can be interpreted as the "wing-like cartilage."
Description
The alar cartilage is a pair of soft, pliable tissues located at the tip of the nose. Each piece of alar cartilage is shaped like a wing, hence the name. They are responsible for the shape of the nostrils and contribute to the overall form of the nose.
Function
The primary function of the alar cartilage is to maintain the shape of the nostrils and provide flexibility to the nose. It allows the nostrils to dilate and contract, facilitating respiration and other nasal functions.
