This chapter focuses on the integumentary system. Included in Chapter 5 is a review of structure and function of the integumentary system, and how this system responds to injuries and the effects of aging. The integumentary system consists of the cutaneous membrane, (which includes the epidermis, dermis, and the accessory structures) and the subcutaneous layer, which stabilizes the skin's position against underlying organs and tissues.
