The skin is the largest organ of the body, accounting for about 15% of the total adult body weight. It performs many vital functions, including protection against external physical, chemical, and biologic assailants, as well as prevention of excess water loss from the body and a role in thermoregulation. The skin is continuous, with the mucous ...
The skin is the largest organ in the body, covering its entire external surface. The skin has 3 layers—the epidermis, dermis, and hypodermis, which have different anatomical structures and functions (see Image. Cross Section, Layers of the Skin). The skin's structure comprises an intricate network that serves as the body's initial barrier against pathogens, ultraviolet (UV) light, chemicals ...
Skin. As the body’s largest organ, skin protects against germs, regulates body temperature and enables touch (tactile) sensations. The skin’s main layers include the epidermis, dermis and hypodermis and is prone to many problems, including skin cancer, acne, wrinkles and rashes. Get Dermatology Care. Make an Appointment.
The epidermis is the thin outer layer of the skin. It consists of 2 primary types of cells: Keratinocytes. Keratinocytes comprise about 90% of the epidermis and are responsible for its structure and barrier functions. Melanocytes. Melanocytes are found at the base of the epidermis and make melanin. This gives the skin its color.
The skin or the integumentary system is the largest organ of the body that has many important functions in physiology. It protects the body from infections, helps in thermoregulation, and contains nerve receptors that detect pain, sensation, and pressure. The integumentary system is divided into three major components including the epidermis ...
The skin is the body's largest and primary protective organ, covering its entire external surface and serving as a first-order physical barrier against the environment. Its functions include temperature regulation and protection against ultraviolet (UV) light, trauma, pathogens, microorganisms, and toxins. The skin also plays a role in immunologic surveillance, sensory perception, control of ...
“Thick skin” is found only on the palms of the hands and the soles of the feet. It has a fifth layer, called the stratum lucidum, located between the stratum corneum and the stratum granulosum (Figure 5.1.2). Figure 5.1.2 – Thin Skin versus Thick Skin: These slides show cross-sections of the epidermis and dermis of (a) thin and (b) thick ...
The skin has three basic layers, each with a different role. The number of skin layers that exists depends on how you count them. You have three main layers of skin—the epidermis, dermis, and hypodermis (subcutaneous tissue). Within these layers are additional layers. If you count the layers within the layers, the skin has eight or even 10 ...
Human skin is the largest multifunctional organ of the body, and knowledge of its structure and function is essential to clinicians and researchers. The skin has two layers, the epidermis and dermis, separated by a basement membrane zone. It provides protection, sensation, thermoregulation, biochemi …
Skin is the most extensive organ of the body and consists of three layers: epidermis, dermis, and subcutaneous fat (Fig. 1.1). The outermost layer, the epidermis, consists of viable keratinocytes, which are bound by a keratin membrane, the stratum corneum. The complete cycle of keratinocytes renovation lasts about 30 days.
dermis. human skin, in human anatomy, the covering, or integument, of the body’s surface that both provides protection and receives sensory stimuli from the external environment. The skin consists of three layers of tissue: the epidermis, an outermost layer that contains the primary protective structure, the stratum corneum; the dermis, a ...
The skin is the outermost and largest organ making up almost a fifth of the weight of the human body. Important functions of the skin are protection, thermoregulation and reception, and mediation of mechanical, nociceptive and potentially chemical stimuli. The skin consists of an outer five-layered epidermis and an inner two-layered dermis.
The skin is the largest organ in the human body and comprises approximately 8% of total body mass. It is a versatile structure with a wide range of functions; and its exact composition varies across different regions of the body’s surface. In this article, we will discuss the function, gross structure and ultrastructure of our skin.
Undoubtedly, the skin is the largest organ in the human body; literally covering you from head to toe. The organ constitutes almost 8-20% of body mass and has a surface area of approximately 1.6 to 1.8 m2, in an adult. It is comprised of three major layers: epidermis, dermis and hypodermis, which contain certain sublayers.
Skin that has four layers of cells is referred to as “thin skin.”. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. Most of the skin can be classified as thin skin. “Thick skin” is found only on the palms of the hands and the soles of the feet.
Scrotal anatomy. The scrotum is a pigmented external sac of skin and muscle that physically protects and facilitates temperature regulation of the testes to ensure optimal spermatogenesis. It is formed from fusion of the left and right labioscrotal folds, and has a septum that separates the two halves (Figure 1).

This article will overview the anatomy and physiology of skin, skin's response to injury, normal tissue healing, the phases of acute wound healing, and the altered healing in chronic wounds. Wound healing is complex and involves the coordination of many intricate processes. There are many factors that can impact wound healing, both positively ...
The skin is continuous with the membranes lining the body orifices and in certain areas contains accessory structures such as glands, hair and nails. A detailed description of the structure of the skin is given on pages 1–7 of this issue. The skin is the interface between the body and the environment. It has a number of physiological ...
Description. Skin is part of the integumentary system and is the largest and primary protective organ of the human body [1]. It covers the body's entire external surface and serves as a first-order physical barrier against the outer environment.
