| Question | Answer |
|---|---|
| paronychium | soft tissue surrounding border of nail |
| sebaceous glands | creates sebum (oil) |
| stratum corneum | superfiscal layer of epidermis renews itself 3-4 days dead cells filled with keratin |
| etilogy | cause of (study of the) |
| ceruman | earwax |
| dermis | largest section of skin collogen elastin and pores sudiferous and sebaceous glands |
| pores | blood vessels & nerves pain & touch receptors opens, excretes water & oils |
| appendages | hair and nails |
| hair root | stem begins |
| lunula | base of nail half moon shaped air and keratine = white color |
| nails | includes nail bed, paronychium nail plate, lunula, cuticle |
| nails grow | fingernails 3-5 mo toenails 12-18 mo |
| pilomotor muscles | move hair follicles goosebumps = warmth |
| melanin | produced by melanocytes gives skin pigmentation considered natural sunscreen |
| basal | deepest layer of epidermis cells grow multiply and rise melanocytes live here |
| follicle | sac where hair grows from |
| avascular | no blood vessels |
| aneural | no nerves |
| sudiferous glands | sweat glands (oil and water) |
| nail plate | body of nail attached to skin |
| rule of 9's | a way of calculating severity of burns using weight of pt and percentage of area affected |
| 1st degree burns | epidermis only redness and swelling heals within 2 days |
| 2nd degree burns | epidermis and dermis redness, swelling blisters, and pain |
| hair | avascular & aneural epidermis grows 1/2 inch per month melanin gives hair color |
| hair | includes follicle, hair fiber hair root, melanocytes melanin+iron = red hair |
| melanocytes | gives hair color |
| cuticle | narrow band of epidermis contains keratin |
| epidermis | avascular & aneural 2 layers (stratified) stratum corneum & basalt |
| shedding | sloughing desquamation |
| 3rd degree burn | whole thickness of "fatty layers" necrosis |
| necrosis | death to body tissue |
| nail bed | point of attachment |
| hair fiber | hard protein made of keratin |
| subcutaneous | reg temp & moisture contains fat, water and salts contains adipocytes |
| adipocytes | fat cells |
| diaphoresis | sweating |
| acne | inflammation of sebaceous glands etiology - obstruction of pores |
| impetego | pink fluid filled lesions around mouth and nose etiology - staph infection (contagious) |
| seborrahec dermatitus | dandruff etiology - dry or oily scalp |
| contact dermatitus | inflammation of the skin umbrella diagnosis unknown etiology |
| boils | inflammation of the hair follicle etiology - staph bacteria |
| paromychia | swelling of the tissue etiology - nail biting, picking of nails |
| poison ivy, oak and sumac | type of dermititus etiology - plants |
| psoriasis | chronic red lesions covered by silver scales etiology - believed caused by stress |
| herpes/cold sores | small fliud filled sacs etiology - herpes simplex virus |
| mycosis | tinea pedis (athletes foot,jock itch) tinea corpus (ringworm)etiology - warm dark moist conditions |
| onycholysis | detachment of nail plate from nail bed etiology - infection or trauma |
