ABSTRACT The plantaris longus tendon (PLT) in bullfrog develops a fibrocartilage‐like tissue in the area that is functionally subject to compressive forces. The aim of this study was to analyze the modifications of the pressure‐bearing region in bullfrog PLT with different ages (7, 180, and 1,080 da...
