I am so excited to take part in this, my second, A – Z Challenge! Last year I did the challenge using “recipes” as my inspiration. Well, this year I’m going to draw on my nursing background and use “parts of the human body” as my inspiration! Hmmm…a part of the body that starts with “Q”, “X” or “Z”….
It should be a lot of fun and I’m looking forward to seeing how everyone interprets the Challenge!
So, without further ado, “W” is for Wrinkles…I know, I know…some of you don’t have these yet, but trust me, they’re there and just waiting for the perfect time to make a grand entrance!
Just ask this poor little cat!
The skin is made up of 3 layers -
Epidermis - is the outer layer and functions as a barrier to the external environment
Dermis – is the second layer of skin and contains the structural element of the skin, the connective tissue.
Subcutaneous Tissue – is the bottom layer of skin and contains fat cells. These fat cells provide insulation to the body and make the skin look plump or full.
- As a person ages the epidermal cells become thinner and less sticky. The thinner cells make the skin look noticeably thinner.
- The decreased stickiness of the cells decreases the effectiveness of the barrier function allowing moisture to be released instead of being kept in the skin. This causes dryness.
- The number of epidermal cells decreases by 10% per decade and they divide more slowly as we age making the skin less able to repair itself quickly.
- Wrinkling in the skin is mainly the result of, habitual facial expressions, aging, sun damage, smoking, and poor hydration.
- With prolonged water exposure, the outer layer of skin starts to absorb water. The skin doesn’t expand evenly, causing it to wrinkle. Depletion of water in the body, as occurs with dehydration, can also cause this puckering of the skin.
“W” is also for:
white matter Bundles of myelinated axons located in the central nervous system.
white blood cells Or leukocytes are cells of the immune system involved in defending the body against both infectious disease and foreign materials.
