Comparative Functional Morphology of the Skeletal Forelimb, Pectoral Girdle, and Sternum in Japanese Native Domestic Fowls

摘要: This study aims to understand the relationships among morphological characteristics, their functional roles, and breeder preferences in Japanese native fowls. We analyzed compared shapes sizes of skeletal forelimb, pectoral girdle, sternum six breeds: Chabo, Oh-Shamo, Onagadori, Shokoku, Tosajidori, Totenko. Because are one bases for composing body appearance movement birds such as flapping, we treated those skeletons. All measurements size were smaller Chabo than other breeds except Tosajidori. The largest measurement values all parameters observed Oh-Shamo. Short wide forelimb bones a short coracoid Chabo. Oh-Shamo was equipped with widely articulated coracoid. Shokoku Totenko possessed longer that constitute thoracic cavity. suggest small bone ornamental fowls contributes toward cute large fighting is correlated masculinity aggressiveness. bones, articulation, corpus create round soft silhouette. prevents from dragging its on ground while walking. articulation considered contribute ability pounce an opponent by flapping during fight. affect outline, producing strong, masculine physical appearance. also characteristics space vocal organs, clavicle air sacs. underlie function each breed.
