the outer, fleshy part of the nostril that helps regulate airflow and contributes to the shape of the nose
The nasal ala, located on each side of the nose, consists of soft, flexible tissue that helps regulate airflow in and out of the nostrils. Its structure includes blood vessels and sebaceous glands, which contribute to the moisturization and warmth of inhaled air. The nasal ala also assists in filtering airborne particles and plays a role in the sense of smell. Additionally, it is involved in facial expressions, contributing to various movements and contours of the nose during different emotional and communicative expressions.
