MICROANATOMY

Detailed explanation-1: -The dermis is a connective tissue layer sandwiched between the epidermis and subcutaneous tissue. The dermis is a fibrous structure composed of collagen, elastic tissue, and other extracellular components that includes vasculature, nerve endings, hair follicles, and glands.

Detailed explanation-2: -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).

Detailed explanation-3: -The dermis contains nerve endings, sweat glands and oil glands (sebaceous glands), hair follicles, and blood vessels. The nerve endings sense pain, touch, pressure, and temperature. Some areas of the skin contain more nerve endings than others.
