The mechanical behavior of the various noncontractile tissues is determined by the proportion of collagen and elastin fibers and by the structural orientationHigh in collagen and low in PGs are designed to resist high tensile loadHigh in PGs could resist compressive loadWhen tensile forces are applied, maximum elongation of collagen is less than 10%, whereas elastin may lengthen 150% and return to its original configuration.Collagen is five times as strong as elastinThree types of collagen fibers:In tendon, more parallel and can resist the greatest tensile load.In skin, random and weakest in resisting tensionIn ligament, capsule, and fasciae, the collagen fibers vary between the two extremes and resist multidirectional forces
