Biology Diagrams Skin is part of the integumentary system and considered to be the largest organ of the human body. There are three main layers of skin: the epidermis, the dermis, and the hypodermis (subcutaneous fat). The focus of this topic is on the epidermal and dermal layers of skin. Skin appendages such as sweat glands, hair follicles, and sebaceous glands are reviewed in-depth elsewhere.[1]
The layers of the skin make up the body's largest organ, providing a crucial barrier between the internal structures and the external environment.This complex, multi-layered tissue is essential for protection, sensation, temperature regulation, and immune defense. Understanding the structure and function of the layers of the skin is key to appreciating its role in human health and physiology.

CHAPTER 7 Skin and its appendages. In this chapter, the types and functions of skin in different parts of the body are described first, followed by the microstructure of the epidermis and dermis, and the appendages of skin including the pilosebaceous units and the sweat glands and nails. The basal or deepest layer of cells, adjacent to the The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue (Figure 5.1.1). The most superficial layer of the skin is the epidermis which is attached to the deeper dermis. Accessory structures, hair, glands, and nails, are found associated with the skin.

The skin is the largest organ of the body, covering an area of approximately 2 m 2.The skin is composed of the cutis (including the dermis and epidermis), subcutaneous tissue, and skin appendages.The epidermis, which is derived from ectoderm, is the outermost layer of the skin and is mainly composed of keratinocytes.The dermis, which is derived from mesoderm, is located underneath the
