1. The anterior appendage of a bird. 2. In anatomy, ala.ala (1);
angel's w. a deformity in which both scapulae project conspicuously. See also winged scapula.
ashen w. vagal trigone
w. of crista galli a small lateral expansion of the ethmoid bone from the front of the crista galli on each side that articulates with the frontal bone and forms the foramen cecum.ala cristae galli [NA], alar process;
gray w. vagal trigone
greater w. of sphenoid bone strong squamous processes extending in a broad superolateral curve from the body of the sphenoid bone. The greater w. presents these suraces (facies): 1) cerebral surface: forms anterior third of the floor of the lateral portions of the middle cranial fossa; 2) temporal surface: forms the deepest portion of the temporal fossa; 3) infratemporal surface, forms the "roof" of the infratemporal fossa; 4) orbital surface: forms posterolateral wall of orbit. The greater w. forms the inferior border of the supraorbital fissure, and is perforated at its root by foramina rotundum ovale, and spinosum and the pterygoid canal.ala major ossis sphenoidalis [NA], ala temporalis;
w. of ilium the upper flaring portion of the ilium.ala ossis ilii [NA];
Ingrassia's w. lesser w. of sphenoid bone
lesser w. of sphenoid bone one of a bilateral pair of triangular, pointed plates extending laterally from the anterolateral body of the sphenoid bone. Forming the posteriormost portion of the floor of the anterior cranial fossa, their sharp posterior edge forms the sphenoidal ridge separating anterior and middle cranial fossae. The medial end of the lesser w. attaches to the body by means of two pedicles, thus forming the optic canal. The w. itself forms the superior margin of the supraorbital fissure.ala minor ossis sphenoidalis [NA], ala orbitalis, Ingrassia's apophysis, Ingrassia's w;
w. of nose the outer more or less flaring wall of each nostril.ala nasi [NA], pinna nasi;
w. of sacrum the upper surface of the lateral part of the sacrum adjacent to the body.ala sacralis [NA];
