NAILS/age related skin changes/hormonal effects/skin repair

QuestionAnswer
nail body visible portion of nail
nail root portion of nail lying underneath skin
lunula pale crescent of nail near root
nail bed epidermis beneath nail
eponychium part of stratum corneum overlying proximal part of nail
hyponychium part of stratum corneum underneath distal part of nail
decreased germinative cell activity epidermis thins
decreased sebaceous and sweat gland activity decreased perspiration, drier skin
decreased melanocyte activity gray/white hairs, increased sunburn risk
decreased number of dendritic cells decreased immune response
decreased number of active hair follicles fewer hairs
decreased blood flow to dermis decreased ability to lose body heat
[Hormonal effects on integument] thyroid gland hormones maintain blood flow to dermis
[Hormonal effects on integument] glucocorticoids loosen connections between keratinocytes
[Hormonal effects on integument] sex hormones, epidermal growth factor stimulate epidermal cell divisions
[Hormonal effects on integument] growth hormone stimulates fibroblast activity and collagen synthesis
[Steps in integumentary repair] initial injury bleeding, mast cells release histamine
histamine inflammatory response
[Steps in integumentary repair] after several hours a. blood clot → scab, b. macrophages phagocytize debris, c. granulation tissue starts to form
[Steps in integumentary repair] after one week a. epidermal cells migrate underneath scab, b. fibroblasts produce collagen fibers in dermis
[Steps in integumentary repair] after several weeks a. epidermal repair is complete, b. scar tissue completes repair process in dermis

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
