What does the term 'corium' refer to?

The term 'corium' refers specifically to the true skin, which is also known as the dermis. This layer is crucial because it contains essential structures such as blood vessels, nerve endings, hair follicles, and connective tissue, all of which play vital roles in skin function and health. The dermis supports the epidermis, the outermost skin layer, and is responsible for much of the skin's strength and elasticity. Understanding this term is fundamental in fields such as dermatology and aesthetic practices, where knowledge of skin anatomy is essential for effective treatment approaches.
