  5. 5. SKIN • Skin is the external barrier of the body, both physical and immunological • skin is the largest organ of the body, it constitutes about 16% of body weight • its total surface area is about 1.2-2.2 m2 • function: protection, sensory reception, excretion and thermoregulation 5
  6. 6. SKIN STRUCTURE 6
  7. 7. SKIN PHYSIOLOGY The skin is the outer most layer of the body. It is constituted of 2 layers : • Epidermis: Stratum corneum : It consist of epidermal cells lipophilic nature The membrane provides about 10 -15 layers of flattened keratinized dead cells It is 10 um when it is dry. But It can take up moisture up to 15 -20 % When occlusive dressing / cream applied over the skin prevent the evaporation of water It plays a role in controlling the percutaneous absorption of chemical substance 7
  8. 8. • Stratum lucidum: It is thin translucent layer . • Stratum granulosum : It is consist of keratin protein. • Stratum spinosum : It consist of flattened polygonal cells. • Stratum germinativum : It consist of melanocytes • Dermis: Dermis /corium It consist of dense network of structural protein fibres .It is about 0.2-0.3mm thickness It contains blood vessels,lymphatic vessels, nerve ending 8
  9. 9. Skin Functions • Sebaceous gland Oil is produced in the sebaceous gland , this production is stimulated by hormones. Oil flows into the hair follicle then onto the skin surface • Epidermis barrier – Waterproofs – Protect from UV • Dermis – Sweat glands – Blood vessels – Nerve endings 9
  10. 10. Some common disorders of skin • Hyper pigmentation: This disorder due to abnormal pigmentation or increased local synthesis of melanin in the epidermis . This can be further stimulated by exposure to UV radiation. • Hypopigmentation: This disorder due to less pigmentation of melanin . which is called as vitiligo. Acne( pimples)& prickly heat (miliaria) Malfunction of sebaceous gland and sweat gland Skin scaling is caused by dandruff and psoriasis 10
  11. 11. • Psoriasis: It is formation of scaly red patches particularly on the extensor surface of the body. • Dandruff : Flaking of s.corneum and mostly occurs on scalp due to microbial infection . • Effects of aging of the skin: Aging affects the character and function of the skin . cosmetics are used to partially repair , mask or overcome such changes Decrease in elasticity of the skin cause wrinkles due to less blood supply. 11
