1 The epidermis is the epithelial tissue layer of skin. 2  Hair follicles, sebaceous glands, and sweat glands are epithelial invaginations from the epidermis. 3  The dermis is the connective tissue layer of skin.  Embedded within the dermis are hair follicles and sweat glands as well as blood vessels and sensory nerve endings.
The Dermis. The dermis is located beneath the epidermis and is the thickest of the three layers of the skin (1.5 to 4 mm thick), making up approximately 90 percent of the thickness of the skin.
