Structure of the skin
In
n order to help you to understand how skin breakdown can happen, it is essential to have some understanding of how the skin is made up and what its’ its functions are.
The skin is the largest organ in the body, both by weight and surface area. It acts as a protective layer that covers the entire body, also acting as a two-way two barrier to prevent the inward or outward passage of water and electrolytes. The skin is involved in maintaining body temperature. It gathers sensory information from the environment and nd plays an active role in immunity, which acts to protect us from disease. The skin has many functions and in order to understand these it is helpful to gain an understanding of the structure of the skin.

Cross section of the structure of skin
The skin is a complex structure, but is basically made up from three layers known as the:




Epidermis
Dermis
Subcutaneous layer

The epidermis
The epidermis is the outer surface of the skin, and is made up from five layers, these being from top to bottom the:






Stratum corneum (horny layer) – the outermost surface of the skin
Stratum licidum (clear layer)
Stratum granulosum (granular layer)
Stratum spinosum (prickle cell layer)
Stratum basale (basal layer) – the layer just above the dermis

The bottom layer, the stratum basale, generates new cells that migrate slowly through the layers to the top layer, the stratum corneum. As the cells move into the higher layers, they flatten and

    The video “Skin Cancer Medical Animation” is about the integumentary system (skin) and how skin cancer is developed. Compared to majority of the organ systems, the integumentary system is one of the largest organ systems that play an important role in protection and maintenance of body temperature and fluids (Cancer Treatment Center of America, 2007). According to the video, the skin is composed of three layers with each layer having different types of cells. The first layer is the Epidermis which is composed of basal, squamous, and melanocytes cells, its function is to shield and defend the internal layers of tissues and organs from having too much contact to UV sunlight. The second layer is the dermis and it is composed of “blood vessels, connective tissue, hair follicles, and sweat glands” and the…

    The skin technically consists of 2 basic layers called the epidermis and the dermis. Although, there is a layer beneath the dermis called the subcutaneous layer, it is not a true part of the integumentary system. The epidermis is the outermost layer of the skin, providing the waterproof covering. The dermis, or corium is the thicker, second layer containing nerve endings, muscles, hair follicles, oil and sweat glands. The subcutaneous layer or hypodermal layer,…

    Unless enough care is taken it will become cracked or inflamed. Unclean skin favors the development of pathogenic organisms. The constantly peeling off dead cells of the epidermis mix with the secretions of the sweat and sebaceous glands and the dust found on the skin to form a filthy layer on its surface. If not washed away the dirt and dead skin slurry begins to decompose emitting a foul smell. Functions of the skin are disturbed when it is dirty and it becomes more easily damaged. The release of antibacterial compounds decreases. Dirty skin is more prone to develop infections. Cosmetics should be used carefully because these may cause allergic reactions. Each season requires suitable clothing in order to facilitate the evaporation of the sweat. Sunlight, water and air play an important role in keeping the skin healthy.…

    The deepest layer of the epidermis is the stratum basale. Keratinocytes form in this layer and then move up through the epidermis to the most superficial layer, where they are shed as dead skin cells. The stratum basale also holds melanocytes. Melanoctytes are needed to protect the skin from UV radiation and determine skin color. The second deepest layer give the skin its strength and flexibility. This layer is called the stratum spinosum. The third most superficial layer is the stratum granulosum. Part of the production of keratin takes place in this layer. The next layer is the stratum lucidum. This layer is only found on the plams of hands, soles of feet, and finger/toe tips. The most superficial layer of the epidermis is the stratum corneum.…

    The skin is the largest organ of the body. The skin and its components including hair, nails, sweat glands, and oil glands, make up the integumentary system. The main functions of the skin is to provide protection to the body and organ systems. It protects the body from external factors such as bacteria, chemicals, and temperature. The skin contains secretions that can kill bacteria, and the pigment melanin provides a chemical defense against ultraviolet light that can damage skin cells. The skin also helps control body temperature.…
