The epidermis contains no blood vessels, and cells in the deepest layers are nourished by diffusion from blood capillaries extending to the upper layers of the dermis. It can appear anywhere on the body as a mole that has irregularly shaped edges, asymmetrical shapes, and multiple colors. In People of Color, melanoma often appears in areas that are less exposed to the sun. Todar K. "Immune Defense against Bacterial Pathogens: Innate Immunity". textbookofbacteriology.net . Retrieved 19 April 2017. Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin cutis 'skin'). In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue and guards the underlying muscles, bones, ligaments, and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. [1] Skin (including cutaneous and subcutaneous tissues) plays crucial roles in formation, structure, and function of extraskeletal apparatus such as horns of bovids (e.g., cattle) and rhinos, cervids' antlers, giraffids' ossicones, armadillos' osteoderm, and os penis/ os clitoris.

Keratinocytes are the major cells, constituting 95% of the epidermis, [11] while Merkel cells, melanocytes and Langerhans cells are also present. The epidermis can be further subdivided into the following strata or layers (beginning with the outermost layer): [12] It harbors many mechanoreceptors (nerve endings) that provide the sense of touch and heat through nociceptors and thermoreceptors. It also contains the hair follicles, sweat glands, sebaceous glands, apocrine glands, lymphatic vessels and blood vessels. The blood vessels in the dermis provide nourishment and waste removal from its own cells as well as for the epidermis. Abdo J, Sopko N, Milner S.

Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Dermis and subcutaneous tissues are thought to contain germinative cells involved in formation of horns, osteoderm, and other extra-skeletal apparatus in mammals. [2]

Over the course of your life, you should pay attention to all parts of your skin. Familiarize yourself with it, so you'll notice any changes that might occur, such as different moles or patches that might indicate skin cancer. Whenever you have a question or concern, make sure you see your doctor. How Does My Skin Work? Vitiligo is characterized by loss of pigment in the skin due to autoimmune destruction of the cells that give skin its color. Alibardi, Lorenzo (15 August 2003).

Many people are tempted to try to wash the oil off – but this can result in the skin feeling dry, which will actually stimulate it to produce more oil! Skin plays an important immunity role in protecting the body against pathogens and excessive water loss. Its other functions are insulation, temperature regulation, sensation, synthesis of vitamin D, and the protection of vitamin B folates. Severely damaged skin will try to heal by forming scar tissue. This is often discoloured and depigmented. Fever, chills, and red streaking from the rash might be symptoms of a serious infection requiring medical attention.The skin has up to seven layers of ectodermal tissue and guards the underlying muscles, bones, ligaments and internal organs. [8] The epidermis is divided into several layers, where cells are formed through mitosis at the innermost layers. They move up the strata changing shape and composition as they differentiate and become filled with keratin. After reaching the top layer stratum corneum they are eventually 'sloughed off', or desquamated. This process is called keratinization and takes place within weeks. Storage and synthesis: acts as a storage centre for lipids and water, as well as a means of synthesis of vitamin D by action of UV on certain parts of the skin.
