Among other things, skin ageing is noted by a decrease in volume and elasticity. There are many internal and external causes to skin ageing. For example, ageing skin receives less blood flow and lower glandular activity. Melanocytes. Melanocytes are found at the base of the epidermis and make melanin. This gives the skin its color. Blood capillaries are found beneath the epidermis and are linked to an arteriole and a venule. Arterial shunt vessels may bypass the network in ears, the nose and fingertips. The word skin originally only referred to dressed and tanned animal hide and the usual word for human skin was hide. Hives on darker skin can appear raised or inflamed and might be slightly darker or lighter than your natural skin color. On lighter skin, hives usually appear red.

Intensifying this effect is the decreasing ability of skin to heal itself as a person ages. They may be smaller than 1 centimeter (cm) (vesicle) or larger than 1 cm (bulla) and can occur alone or in groups. Itchy skin is not usually a sign of anything serious. You can often treat it yourself and it will usually go away after a few weeks. How to treat itchy skin yourself It also causes a red rash, which spreads from the face down the body 3 to 5 days after the first symptoms appear. This rash might be more difficult to see on darker skin. The subcutaneous tissue (also hypodermis and subcutis) is not part of the skin, but lies below the dermis of the cutis. Its purpose is to attach the skin to underlying bone and muscle as well as supplying it with blood vessels and nerves. It consists of loose connective tissue, adipose tissue and elastin. The main cell types are fibroblasts, macrophages and adipocytes (subcutaneous tissue contains 50% of body fat). Fat serves as padding and insulation for the body.

C is correct. An injury to the epidermis often causes pain, and leaves the area vulnerable to infection. However, structures such as nerves, blood vessels, sebaceous glands, and hair follicles are located deep in the dermis.There are several serious skin conditions. In particular, melanoma is a type of skin cancer that can be especially dangerous, as it could spread to other parts of the body if not caught early. Cellulitis and latex allergy can also be very serious if left untreated. Which skin disease is not curable? 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. [2] You lose collagen and elastin as you age. This causes the skin’s middle layer (dermis) to get thinner. As a result, the skin may sag and develop wrinkles. Carotene: This pigment is yellow to orange in colour. It is present in the stratum corneum and fat cells of dermis and superficial fascia. a b Proksch E, Brandner JM, Jensen JM (December 2008).

Skin layers, of both hairy and hairless skin Cell Count and Cell Mass [ edit ] Skin Cell Table [ edit ] Human skin shows high skin colour variety from the darkest brown to the lightest pinkish-white hues. Human skin shows higher variation in colour than any other single mammalian species and is the result of natural selection. Skin pigmentation in humans evolved to primarily regulate the amount of ultraviolet radiation (UVR) penetrating the skin, controlling its biochemical effects. [20]

Skin is the largest organ in the body andcovers the body's entire external surface. It is made up of three layers, the epidermis, dermis, and the hypodermis, all three of which vary significantly in their anatomy and function. The skin's structure is made up of an intricate network which serves as the body’s initial barrieragainst pathogens, UV light, and chemicals, and mechanical injury. It also regulates temperature and the amount of water released into the environment. This article discusses the relevant anatomical structures of the skin’s epidermal layer, its structure, function, embryology, vascular supply, innervation, surgical considerations, and clinical relevance. This causes a rash, which may occur within minutes to hours after exposure to a latex product. It may be less visible on darker skin or appear lighter or darker than surrounding tissue.
