The patagium is a membranous structure that assists an animal in gliding or flight. The structure is found in bats, birds, some dromaeosaurs, pterosaurs, and gliding mammals. ==Bats== In bats, the skin forming the surface of the wing is an extension of the skin of the abdomen that runs to the tip of each digit, uniting the forelimb with the body. The patagium of a bat has four distinct parts: #Propatagium: the patagium present from the neck to the first digit #Dactylopatagium: the portion found within the digits #Plagiopatagium: the portion found between the last digit and the hindlimbs #Uropatagium: the posterior portion of the body between the two hindlimbs 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Patagium」の詳細全文を読む スポンサード リンク
