The document discusses the structure and functions of human skin. It describes the five layers of the epidermis from the corneum to basale layers. It also mentions the skin adnexa including hair follicles, sebaceous glands, and sweat glands. The key functions of skin are listed as protection, temperature and water homeostasis, excretion of urea/NaCl/K, melanin formation, and serving as a sensory organ. The document concludes by noting some clinical points about conditions like sebaceous cysts, ulcers, sinuses/fistulas, and skin grafts.
