<p>The functions of the skin and accessory structures include protecting underlying tissues and organs against impact, abrasion, fluid loss, and chemical attack; producing melanin to protect underlying tissue from UV radiation and for skin pigmentation; producing keratin to protect against abrasion and serve as a water repellent; storing lipids in adipocytes in the dermis and in adipose tissue in the subcutaneous layer; detecting touch, pressure, pain, and temperature stimuli and relaying that information to the nervous system; and contributing to thermoregulation through insulation and evaporative cooling.</p> Signup and view all the answers
