Skin covers the outer surface of the body and is the largest organ. Skin and it’s accessory structures (hair, sweat glands, sebaceous glands, and nails) make up the integumentary system. Its primary functions are to protect the body from the environment and prevent water loss. Skin is classified into two types: Thick skin which covers the palms of the hands and the soles of the feet. On the other hand, thin skin covers the rest of the body. Scalp hairs arise from hair follicles extending deep into the dermis. Hair follicles are invaginations of the epidermis that form multilayered cylinders of cells.
