body. The main type of cells which make up the epidermis are Merkel cells, keratinocytes, with melanocytes and Langerhans cells also present. 6, its other functions are insulation, temperature regulation, sensation, synthesis of vitamin D, and the protection of vitamin B folates. Maton, Anthea; Jean Hopkins; Charles William McLaughlin; Susan Johnson; Maryanna Quon Warner; David LaHart; Jill. Clinical significance edit Further information: skin disease Diseases of the skin include skin infections and skin neoplasms (including skin cancer). This is often discolored and depigmented. A b c d Osinski, Marek; Luke Mortensen; Hong Zheng; Renea Faulknor; Anna De Benedetto; Lisa Beck; Lisa. It is composed of dense irregular connective tissue, and receives its name from the dense concentration of collagenous, elastic, and reticular fibers that weave throughout. Biochemically pigs contain dermal collagen and elastic content that is more similar to humans than other laboratory animals. The epidermis can be further subdivided into the following strata (beginning with the outermost layer corneum, lucidum (only in palms of hands and bottoms of feet granulosum, spinosum, basale. 35 One study compared the two shapes and recorded data that showed spherical particles located deep in the epidermis and dermis whereas ellipsoidal particles were mainly found in the stratum corneum and epidermal layers.
Biology The Skin
Aesthetics and the Postmodernity communication : others see our skin and can assess our mood, physical state and attractiveness. Edqvist, Per-Henrik.; Fagerberg, Linn; Hallström, Björn.; Danielsson, Angelika; Edlund, Karolina; Uhln, Mathias; Pontn, Fredrik. 10 The average square inch (6.5 cm) of skin holds 650 sweat glands, 20 blood vessels, 60,000 melanocytes, and more than 1,000 nerve endings. Melanin : It is brown in color and present in the basal layer of the epidermis. Available at "Nanotechnology Information Center: Properties, Applications, Research, and Safety Guidelines". It is present in the stratum corneum and fat cells of dermis and superficial fascia. Wound healing - When a minor burn or abrasion occurs basal cells of the epidermis break away from the basement membrane and migrate across the wound. . Nanomedical researchers seek to target the epidermis and other layers of active cell division where nanoparticles can interact directly with cells that have lost their growth-control mechanisms ( cancer cells ).
