The unique fibrillar arrangement of the bullfrog pressure-bearing tendon as an indicative of great functional deformability.


The fiber distribution and ultrastructure in the plantaris longus pressure-bearing tendon of the bullfrog were investigated. The tension region of the tendon showed a predominant parallel distribution of collagen fibers, but three main zones with different crimp parameters were identified with the use of the polarizing microscope. The compression region… (More)
