Detailed explanation-2: -The dermis is found beneath the basement membrane of the epidermis and is the main structural component of the skin. The dermis consists of a richly vascularized and highly innervated connective tissue that supports the epidermis and the skin appendages (hair follicles, sebaceous glands and sweat glands).
