The arising patterns of the bovine diaphragmatic crura which consists of right and left crura in the lumbar portion of diaphragm, and the relative muscle weight of each crus were investigated. Diaphragm was obtained from 61 just before birth stage bovine fetus. The arising formation of the diaphragmatic crura in this study achieved its adults form. The arising patterns of the diaphragmatic crura were classified into 3 types according to the pattern of the cranial end of attachment of tendons in the right and left crura. The cranial end of the attachment of tendon is cranial in the right crus than in the left, shows the highest relative muscle weight of the right crus. The cranial end of the attachment of tendon is cranial in the left crus than in the right, shows the highest relative muscle weight of the left crus.
