Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
Keratinocytes- The most abundant cells of the epidermis. b. Keratin- The protein found in the epidermis that is responsible for toughening the skin. c. Merkel disc- Cells plus a disc-like sensory nerve ending that functions as a sensory receptor for touch.
