Tendon also have a role in the tensile properties of tendon. The structure of tendon is effectively a fibre composite material, built as a series of hierarchical levels. At each level of the hierarchy, the collagen units are bound together by either collagen crosslinks, or the proteoglycans, to create a structure highly resistant to tensile load. The elongation and the strain of the collagen fibrils alone have been shown to be much lower than the total elongation and strain of the entire tendon under the same amount of stress, demonstrating that the proteoglycan-rich matrix must also undergo deformation, and stiffening of
What Is the Fastest Thing in the World? What Is the Fastest Thing in the World? What Is the Fastest Thing in the World? is a Greek fairy tale collected by Georgios A. Megas in "Folktales of Greece". It is Aarne-Thompson type 875 and has many Greek and Slavic variants, generally revolving about the exchange of clever answers. This type of tale is the commonest European tale dealing with witty exchanges. In ballad form, the clever answers to the riddles, and the winning of a husband by them, are found in Child ballad 1, "Riddles Wisely Expounded". A brother argue over how they should split their land, some
