Tendons are dense regular connective tissue structures that are defined based on their anatomical position of connecting muscle to bone. The commons features of tendons show remarkable variation in terms of their morphological, molecular and mechanical properties which relates to their specialized function. The sample population was the superficial digital flexure tendon (SDFT) of forty five adult horses. The percentage of experimentally-induced normal tendon was evaluated in cross-section at the maximal area of mid- metacarpal region using Confocal Scanning Laser microscopy techniques (CLSM). The sex distribution was not taken in to a count Furthermore, it is known that, the changes in this structural organization due to aging following tendon degeneration. The complex structures of tendon and distinctive characteristics have been well demonstrated by CLSM Techniques. The tendon structure under CSLM shows a dense, regular connective tissue arrangement that reflects the mechanical requirement of this tissue. This structure is defined by thick, regular bundles of longitudinal collagen fibers arranged in zig-zag conformation. All tendons examined from horses with no history of superficial digital flexure tendinitis and all macroscopically normal. Tendon has a hierarchical structure, with collagen molecules forming fibrils (50–500 nm), which in turn comprise a fascicle (50–300 μm), and fascicles align along the longitudinal axis of the tendon.
