Detailed explanation-1: -Tendons consist nearly exclusively of type I collagen fibers, all aligned along the length of the tendon to provide the tensile strength that is required to transmit forces from muscle to bone.
Detailed explanation-2: -Dense regular connective tissue It is found in areas of the body where large amounts of tensile strength are required, like in ligaments, tendons and aponeurosis. The collagen fibers are densely packed together and arranged in parallel to each other.
Detailed explanation-3: -Our results indicate that collagen alignment can alter pore-size of matrices depending on the polymerization temperature of the collagen. Furthermore, alignment does not affect the macro-scale stiffness but alters the micro-scale stiffness in a temperature independent manner.
Detailed explanation-4: -In general, these molecules either resist tensile and stretching forces or compressing forces. Collagen is the main component that resist tension. Elastic fibers also resist tension but behaves similar to rubber in that it can be stretched and will recoil after the force is removed.
