Detailed explanation-1: -The epidermis functions in skin as first defense line or barrier against environmental impacts, resting on extracellular matrix (ECM) of the dermis underneath. Both compartments are connected by the basement membrane (BM), composed of a set of distinct glycoproteins and proteoglycans.
Detailed explanation-2: -Cutaneous – Outermost protective boundary, skin that is waterproof, stretchable, washable – exposed to air and is a dry membrane – superficial epidermis is composed of keratinizing stratified squamous epithelium and underlying dermis is mostly dense (fibrous) connective tissue.
Detailed explanation-3: -Stratified squamous epithelium: This type of epithelium usually has protective functions, including protection against microorganisms from invading underlying tissue and/or protection against water loss. The outer layer of your skin (the epidermis) is made of stratified squamous epithelial cells.
