[Structuro-functional organization of the fiber network in the human Achilles tendon].
Owing to a complex morphological investigation of the human Achilles tendon, it was possible to distinguish four levels of the structural-functional organization of its fibrous elements and to reveal some regularities of their structure that recur at all the levels. Thus, collagenous molecules, microfibrillae, fibrillae and fibers have a wavy-spiral conformation. This spatial form is stabilized by a complex or a system of transversal connections corresponding to the given level of the organization. In order to maintain integrity (the structural-functional unity) of each level, certain substances of polysaccharide nature take part. Along the course of the long tendinous axis, a re-distribution (branching) of the fibrillar elements is observed at all the levels of the structural-functional organization.
