Skin Flashcards
Dermis
Next layer;dense fibrous, connective tissue
Subcutaneous tissue (hypodermis)
Thick, fat-containing tissue
Basal layer
Deepest region of epidermis; gives rise to all epidermal cells
Collagen
Structural protein in skin/connective tissue
Cuticle
Band of epidermis at base/sides of nail plate
eccrine sweat gland
Most numerous sweat gland in skin
Paronychium
Tissue around nail border
Sebaceous gland
Oil gland in dermis associated w/ hair follicle
Epidermis
Outermost,thin cellular membrane
Wheal
Smooth, slightly elevated, edema
Vesicle
Clear fluid blister
Polyp
Benign growth extending from mucous membrane surface
Macule
Discolored, flat (freckle)
Erosion
Wearing away, loss of epidermis
Nodule
Solid, elevated mass,
Fissure
Slit,groove
Ulcer
Open sore on skin or mucous membrane
Papule
Small,solid elevation, pimple or plaque
Urticaria
Acute allergic reaction w/ red round wheals on skin
Cellulitis
A diffuse acute infection of skin
Eczema (atopic dermatitis)
Inflammation of skin w/ erythematous/ papulovesicular lesions caused by allergy
Exanthematous viral disease
A rash from virus ex. Rubella
Gangrene
Death of tissue w/ loss of blood supply
Impetigo
Contagious pyoderma caused by staph/strep
Psoriasis
Chronic recurrent dermatosis w/ silver gray scales that itch
Scabies
Parasitic (tiny mites)/ infectious pruritus
Scleroderma
Chronic/progressive
disease of skin w/hardening of connective tissue
Systemic lupus erythematosus (SLE)
Inflam. Disease of collagen in skin,joints, internal organs
Urticaria (hives)
Allergic reaction. Red round wheals on skin
Callus
Increased growth of cells in keratin layer from friction on skin
Keloid
Hypertrophied, thickened scar
Keratosis
Thickened area of epidermis
Leukoplakia
White thickened patches on tongue/cheek
Nevus
Pigmented lesion
Verruca
Warts caused by virus
Bacterial analyses
Pus/fluid samples examined to detect microorganisms
Fungal tests
Scrapings for culture/ microscopic exam after treatment w/ KOH
Mohs surgery
Removes thin layers of growth to examine under microscope (basal/ squamous cell)
Skin biopsy
Punch/shave to remove for examination in path lab
Skin test
Test reaction of body to allergen w/ skin test (scratch/patch test)
