AP skin Flashcards
Terms : Hide Images [1]
| 13334233855 | dermal papillae | form the papillary layer interlocking grooves with the epidermis causes finger prints | 0 | |
| 13334247118 | blood vessels | Nourish epidermis & dermis Contains sensory receptors & glands Cells of the immune system | 1 | |
| 13334266520 | Hypodermis | NOT a layer of skin Tissue: adipose & alveolar (variable thickness) LOC: deep to dermis FUNC: insulation, cushioning & energy storage | 2 | |
| 13334286862 | sebaceous glands | oil glands in the skin | 3 | |
| 13334295898 | oil glands (sebaceous glands) | clusters of epithelial cells association with hair follicle LOC: everywhere except palms/soles FUNC: water proofing, inhibit bacteria acne: increased sebum = infection | 4 | |
| 13334328830 | Sweat (sudoriferous) glands | produce sweat, widely distributed in skin to cool temp | 5 | |
| 13334334175 | eccrine sweat glands | present throughout life open to skin surface responds to heat present everywhere | 6 | |
| 13334342980 | apocrine sweat glands | ACTIVE AT PUBERTY Secretion contains lipids & proteins, acted on by bacteria, causing body Oder associated with hair follicles activated by heat or strong emotion | 7 | |
| 13334366204 | Hair | everywhere except palms and soles | 8 | |
| 13334370096 | hair follicle | Epithelial tube into dermis growth by mitosis at hair bulb, kerinocytes die as they are pushed to the surface | 9 | |
| 13334385682 | arrector pili muscle | Smooth muscle contraction (causes goose bumps) Raisies hair shaft to rap warm air | 10 | |
| 13334399357 | hair color | Produced by melanocytes at the hair papilla | 11 | |
| 13334414088 | temperature regulation | negative feedback Control center: HYPOTHALAMUS | 12 | |
| 13334427252 | Normal temperature | 98.6 F or 37 C | 13 | |
| 13334434812 | Increase temperature | Dialation of dermal blood vessels -> warm blood carried to surface | 14 | |
| 13334457968 | Constriction of blood vessels | warm blood diverted to dermis | 15 | |
| 13334492808 | drop in temperature | Constriction of dermal blood veesels -> less heat loss from surface | 16 | |
| 13334510898 | shivering | response to cold; body shakes to turn into body heat | 17 | |
| 13334521250 | fever | hypothalamus changes set point | 18 | |
| 13334530836 | hypo/hyperthermia | hypo: cold hyper: hot Inability to maintain body temp (elders and kids affected most) | 19 | |
| 13334543058 | Skin healing (epidermis) | Heals with new cells produced by stratum basal | 20 | |
| 13334548012 | skin healing (dermis) | Heals with scar tissue produced by fibroblasts | 21 | |
| 13334552824 | scar tissue | The thick, collagenous tissue that forms at an injury site NONFUNCTIONABLE | 22 | |
| 13334562973 | 1st degree burn | Only the epidermis (red, painful, and edema) heals with no scaring | 23 | |
| 13334571710 | 2nd degree burn | epidermis and part of dermis (blistered) heals without scaring unless infected | 24 | |
| 13334579398 | 3rd degree burn | All three layers have been effected skin may slough off heals very slowly with scaring skin grafts usually required | 25 | |
| 13334603734 | wrinkles | decreased flexibility and thickness of dermis loss of fat, collagen fibers and elastic fibers | 26 | |
| 13334614907 | diminished temperature regulation | fewer sweat glands fewer dermal blood vessels | 27 |
