Answer 1

Keratins are not found in the tongue.

Keratins are NOT found in the tongue. Keratin is a cytoskeletal protein that is mainly found in the skin, hair, and nails. It provides strength and protection to these structures. However, the tongue is made up mainly of muscle tissue and does not contain keratin.
