Detailed explanation-1: -Elastic fibers are long, thin, and highly retractile. Elastin, as its name implies, provides elasticity and extensibility to the dermis and assists in recovery from deformation. Elastin is a highly hydrophobic structural protein making up only 2% of the total protein in the dermis.
Detailed explanation-2: -Elastic fibers in the ECM of these tissues provide the resilience to allow recoil after transient stretching. Elastic fibers are predominantly composed of elastin, a highly hydrophobic protein (≈750 amino acids long).
Detailed explanation-3: -Elastic fibres are essential extracellular matrix macromolecules comprising an elastin core surrounded by a mantle of fibrillin-rich microfibrils. They endow connective tissues such as blood vessels, lungs and skin with the critical properties of elasticity and resilience.
