major alar cartilage of nose
major alar cartilage of nose[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 (that is, medial genu) to the lateral edge of the tip lobule (that is, 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.
