[TA] paired cartilages that support the nasal tip, columella, and nostril rims, each consisting of a medial crus within the columella; a middle crus, which extends from the columella's lobular junction (i.e., medial genu) to the lateral edge of the tip lobule (i.e., lateral genu); and a lateral crus that extends toward the pyriform aperture. The axis of the lateral crus normally extends along the line that runs toward the lateral orbital canthus. SYN: cartilago alaris major nasi [TA], greater alar cartilage.
