The elastic fiber is formed from the elastic microfibril (consisting of numerous proteins such as microfibrillar-associated glycoproteins, fibrillin, ... believe that certain defects of any components of the elastic matrix may impair and alter the structural appearance of elastic and collagen fibers.
It’s comprised of very strong fibers that have impressive tensile strength, and is the foundation upon which the outer layer of the skin is anchored. Elastin is not as plentiful in the skin as collagen, but is critical for skin function. It provides softness and elasticity to skin, forming a three-dimensional network between the collagen fibers.

The fibers are capable of extension to approximately twice their length at rest. In contrast to collagen bundles, elastic fibers are wavy, as well as branching . Elastic fibers in the papillary dermis are present either as bundles of microfibrils, oxytalan fibers, or as cross-linked elastin on one hand or as elaunin fibers on the other.
Elastin is a highly elastic protein in connective tissue and allows many tissues in the body to resume their shape after stretching or contracting. Elastin helps skin to return to its original position when it is poked or pinched.
Elastic fibers are composed of elastin and proteins, often referred to as microfibrils, such as fibrillin, because their fibrils are much smaller than the classic collagen fibrils. Elastic fibers must withstand repeated stretching and deformation and must be capable of returning to a relaxed state. Tropoelastin is the precursor to elastin and ...
Collagen fibers, reticular fibers and elastic fibers. A comprehensive understanding from a morphological viewpoint. ... Fibrous components of the extracellular matrix are light-microscopically classified into three types of fibers: collagen, reticular and elastic. The present study reviews the ultrastructure of these fibrous components as based ...
Collagen fibers make up 2 percent of the human body muscles. Theirmain function is to assist with the ability of the muscles to movethe limbs.
