Understanding the Context

Get a labeled human skin diagram and learn about the structure and functions of skin layers. The skin consists of the epidermis, dermis, and hypodermis layers, providing protection, sensation, and regulation of body temperature. The skin diagram labeled shows the accessory structures such as hair follicles, sweat glands, and sebaceous glands. Given below is a well-labeled diagram of skin: The formation of a skin fold named a rete ridge reveals how simple architectural changes reshape tissue mechanics and signalling routes to make a different type of skin structure.
