Vertebrate body is covered by a tough, three-layered body wall consisting of outta integument, middle muscular layer, and inner coelomic epithelium. It displays important morphological and physiological vibrations between different vertebrate groups depending on their adaptations for various Habitat and mode of life. However, being a protective covering, the integument is basically similar in structure in all vertebrates. Histologically skin is made up of two distinct layers one is epidermis And another one is dermis. So take this quiz and increase your knowledge about integument/ skin and its derivatives.
