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 is the second, or middle, layer of a person's skin. It contains fibers of collagen and elastin, which are important proteins. The collagen and elastin in this layer of skin form a durable mesh-like layer.dditionally, the dermis contains sebaceous glands, hair follicles, sweat glands, and nerves. People cannot see the dermis because it is below the epidermis, the top layer of skin, and hidden from view.
