[Answer] What protein makes stratified epithelial tissues resistant to friction?

Answer: Keratin
What protein makes stratified epithelial tissues resistant to friction?

Epithelial tissue is scutoid shaped tightly packed and form a continuous sheet. It has almost no intercellular spaces. All epithelia is usually separated from underlying tissues by an extracellular fibrous basement membrane. The lining of the mouth lung alveoli and kidney tubules are all made of epithelial tissue. The lining of the blood and lymphatic vessels are of a specialised form of epithelium called endothelium.

Keratinized surfaces are protected from absorption by keratin protein. Keratinized epithelium has keratin protein deposited on the surface which makes it impermeable and dry. Examples of keratinized stratified squamous epithelium include skin epidermis of the palm of the hand and sole of the foot and the masticatory mucosa. Gallery

Keratin (/ ˈ k ɛr ə t ɪ n /) is one of a family of fibrous structural proteins known as scleroproteins. α-Keratin is a type of keratin found in vertebrates. It is the key structural material making up scales hair nails feathers horns claws hooves calluses and the outer layer of skin among vertebrates.

Within the ECM community of vocal ligament fibrous proteins such as elastin and collagen are pivotal in maintaining the proper elastic biomechanical property of vocal fold. Elastin fibers impart the flexibility and elasticity of the vocal folds and collagen is responsible for the resistance and r…
