It serves many important functions, including Protecting the body against trauma Regulating body temperature Maintaining water and electrolyte balance Sensing painful and pleasant stimuli Participating in vitamin D synthesis The skin keeps vital chemicals and nutrients in the body while providing a barrier against dangerous substances from entering the body and provides a shield from the harmful effects of ultraviolet radiation emitted by the sun.
In addition, skin color, texture, and folds see Descriptions of Skin Marks, Growths, and Color Changes help mark people as individuals. Anything that interferes with skin function or causes changes in appearance see Effects of Aging on the Skin can have important consequences for physical and mental health.
Many problems that appear on the skin are limited to the skin. Sometimes, however, the skin provides clues to a disorder that affects the entire body. Consequently, doctors often must consider many possible diseases when evaluating skin problems.
They may need to order blood tests or other laboratory tests to look for an internal disease in people who come to them with a skin problem see Diagnosis of Skin Disorders.
Layers of the Skin The skin has three layers: Epidermis Fat layer also called the subcutaneous layer Each layer performs specific tasks. Getting Under the Skin The skin has three layers. Beneath the surface of the skin are nerves, nerve endings, glands, hair follicles, and blood vessels.
Epidermis The epidermis is the relatively thin, tough, outer layer of the skin. Most of the cells in the epidermis are keratinocytes. They originate from cells in the deepest layer of the epidermis called the basal layer.
New keratinocytes slowly migrate up toward the surface of the epidermis. Once the keratinocytes reach the skin surface, they are gradually shed and are replaced by newer cells pushed up from below. The outermost portion of the epidermis, known as the stratum corneum, is relatively waterproof and, when undamaged, prevents most bacteria, viruses, and other foreign substances from entering the body.
The epidermis along with other layers of the skin also protects the internal organs, muscles, nerves, and blood vessels against trauma. In certain areas of the body that require greater protection such as the palms of the hands and the soles of the feetthe outer keratin layer of the epidermis stratum corneum is much thicker.
Scattered throughout the basal layer of the epidermis are cells called melanocytes, which produce the pigment melanin, one of the main contributors to skin color. Melanin's primary function, however, is to filter out ultraviolet radiation from sunlight see Overview of Sunlight and Skin Damagewhich damages DNA, resulting in numerous harmful effects, including skin cancer.
The epidermis also contains Langerhans cells, which are part of the skin's immune system. Although these cells help detect foreign substances and defend the body against infection, they also play a role in the development of skin allergies.
Dermis The dermis, the skin's next layer, is a thick layer of fibrous and elastic tissue made mostly of collagen, with a small but important component of elastin that gives the skin its flexibility and strength. The dermis contains nerve endings, sweat glands and oil sebaceous glands, hair follicles, and blood vessels.
The nerve endings sense pain, touch, pressure, and temperature. Some areas of the skin contain more nerve endings than others. For example, the fingertips and toes contain many nerves and are extremely sensitive to touch.
The sweat glands produce sweat in response to heat and stress. Sweat is composed of water, salt, and other chemicals. As sweat evaporates off the skin, it helps cool the body. Specialized sweat glands in the armpits and the genital region apocrine sweat glands secrete a thick, oily sweat that produces a characteristic body odor when the sweat is digested by the skin bacteria in those areas.
The sebaceous glands secrete sebum into hair follicles. Sebum is an oil, that keeps the skin moist and soft and acts as a barrier against foreign substances.
The hair follicles produce the various types of hair found throughout the body. Hair not only contributes to a person's appearance but has a number of important physical roles, including regulating body temperature, providing protection from injury, and enhancing sensation.
A portion of the follicle also contains stem cells capable of regrowing damaged epidermis.
Consumption and the Consumer Society The average U.S. resident, in a year, consumes pounds of meat, uses pounds of paper, and uses energy equivalent to metric tons of oil. The Rise of Consumer Culture - Consumer culture has developed over the years for many different reasons such as the demise of the social class and embourgeoisement which are both key factors in capitalism and has therefore led to the argument that consumer society merely reflects the rise of capitalism which I plan to discuss within this assignment. paradigm shift in african american funeral customs: looking through the lens of oral history and consumer culture by carol thomas williams (under the direction of john weaver).
The blood vessels of the dermis provide nutrients to the skin and help regulate body temperature. Heat makes the blood vessels enlarge dilateallowing large amounts of blood to circulate near the skin surface, where the heat can be released. Cold makes the blood vessels narrow constrictretaining the body's heat.
Over different parts of the body, the number of nerve endings, sweat glands and sebaceous glands, hair follicles, and blood vessels varies. The top of the head, for example, has many hair follicles, whereas the soles of the feet have none.Notes - Howson, A.

Marshall McLuhan is considered the first father and leading prophet of the electronic age. This article looks at his work of understanding the effects of technology as it related to popular culture, and how this in turn affected human beings and their relations with one another.

When I think about “consumerism of the body,” prostitution comes to mind. I typically think, Well, I’m not involved in that, so I don’t ever hold a consumer attitude towards others, right? Unfortunately, I—and I’m guessing others—fall into a consumer attitude.
