    • Coracoid (Anat) Pertaining to a bone of the shoulder girdle in most birds, reptiles, and amphibians, which is reduced to a process of the scapula in most mammals.
    • Coracoid Shaped like a crow's beak.
    • n Coracoid The coracoid bone or process.

    • coracoid Shaped like a crow's beak.
    • coracoid Pertaining to the coracoid; connected with the coracoid, as, the coracoid ligament.
    • n coracoid The distal or ventral element of the scapular arch, extending from the scapula to or toward the sternum, of whatever size, shape, or position: so named from the fact that in adult man it somewhat resembles the beak of a crow in size and shape. See cut under scapula. In reptiles, birds, and monotrematous mammals the coracoid is a comparatively large, distinct, and independent bone, articulated at one end with the shoulder-blade and at the other with the sternum. (See cuts under hypoclidium and pectoral.) In all mammals above the monotremes it is much reduced, becoming a mere process of the scapula, firmly ankylosed therewith and having no connection with the sternum, but normally having an independent center of ossification. In amphibians the coracoid varies in condition and relations, but when present conforms to the above definition. In batrachians the coracoid is divided by a large membranous space or fontanel into a coracoid proper, which lies behind this space, a persistently cartilaginous epicoracoid, which bounds the space internally, and a precoracoid in front of it. In fishes the term coracoid has been applied to several different parts, on the assumption of their homology with the coracoid of the higher vertebrates (see cut under scapulocoracoid): by Cuvier and his followers, to the teleotemporal; by Owen and others, to the prescapula; by Parker and other late writers, to the hypocoracoid; by Gill, to the inner cartilage of the scapular arch and the bones into which it is disintegrated in the higher fishes. See these names, and also ectocoracoid, epicoracoid, hypercoracoid, precoracoid, procoracoid.
    • n coracoid In ichthyology, a large bone of the shoulder-girdle; the clavicle; not homologous with the coracoid of Agassiz or of Parker, or the coracoideum of Vogt and Yung.
