Explanation:
Detailed explanation-1: -Elastic fibers (or yellow fibers) are an essential component of the extracellular matrix composed of bundles of proteins (elastin) which are produced by a number of different cell types including fibroblasts, endothelial, smooth muscle, and airway epithelial cells.
Detailed explanation-2: -Elastic fibres, consisting of the protein elastin, are yellow in colour and much thinner and less wavy than collagen fibres.
Detailed explanation-3: -Elastic cartilage is histologically similar to hyaline cartilage but contains many yellow elastic fibers lying in a solid matrix. These fibers form bundles that appear dark under a microscope.
