1 The Language Of Medicine Dr. Michael P. Gillespie

2 2

3 3  Name the layers of the skin and the accessory structures associated with the skin.  Build medical words using the combining forms that are related to the specialty of dermatology.  Identify lesions, signs, and symptoms, and pathologic conditions that relate to the skin.

4 4  Describe laboratory tests and clinical procedures that pertain to the skin and recognize relevant abbreviations.  Apply your new knowledge to understanding medical terms in their proper contexts, such as medical reports and records.

5 5 Skin: integumentary system  weighs 8 to10 lbs.  covers 22 sq. ft. in average adult

6 6  Provides protective membrane  Skin glands lubricate and cool the skin  Receptor for sensations  Helps maintain body temperature

7 7 Produces sweat: sweat glands produce watery secretion that evaporates and cools Produces sebum: sebaceous glands produce oily secretion that lubricates skin and hair Receives sensation: pain, temperature, pressure, and touch Thermoregulates: interprets message from heat center in the brain

8 8 Epidermis: outermost, thin cellular membrane Dermis: next layer; dense fibrous, connective tissue Subcutaneous tissue (hypodermis): thick, fat-containing tissue

9 9

10 10

11 11 HAIR: cells filled with the hard protein; keratin  Hair follicles: shafts that hold the hair  Five million hairs on body; 100,000 on head  Melanocytes at the root form the color  Grow.5 inch (1.3 cm) per month  Cutting does not affect growth

12 12

13 13 NAILS : hard keratin plates covering toes and fingers  lunula  cuticle  paronychium

14 14 GLANDS: sebaceous and sweat  Sebaceous glands secrete oily sebum into hair follicle to lubricate.  Sweat glands secrete into pores to moisten and cool.  Both are subject to bacterial growth.

15 15 Sebaceous gland, eccrine sweat gland, and apocrine sweat gland.

24 24 Label the lesions

25 25 Review the lesions

26 26 Alopecia: absence of hair where it normally grows

27 27 Ecchymosis: blue-black marks on the skin

28 28 Petechia: small pinpoint hemorrhage

30 30 Acne: papular and pustular eruption of skin with increased production of sebum

31 31 Burns: injury to tissue due to heat, chemical, electric shock, lightning or radiation. Image shows (A) Second degree burn and (B) Third degree burn.

32 32  Cellulitis: diffuse acute infection of skin  Eczema: inflammation of skin with erythematous and papulovesicular lesions caused by allergy  Exanthematous viral diseases: rash due to virus (for example, rubella)  Gangrene: death of tissue with loss of blood supply

33 33  Impetigo: contagious pyoderma caused by staph or strep  Psoriasis: chronic recurrent dermatosis with silver gray scales that itch  Scabies: parasitic (tiny mites) and infectious pruritus  Scleroderma: chronic and progressive disease of skin with hardening of connective tissue
