Integumentary System

5. - stratified squamous (top layer) epithelium that lacks blood vessels
6. -Half moon shaped part of nail, most actively growing region
12. - contain the melanosome organelle which produces melanin, the amount of which can effect the skin tone of a person.
13. inner layer (collagen, elastic fibers, smooth msucle tissue, nervous tissue, )
14. -Protien abundent in hair, nails)- helps structure/strength of skin/nails
17. - deepest layer of skin - place of cell division/growth (1 space)
19. - Collagen, elastic fibers within gel-like extracellular matrix (1 space)
20. - respond to temperature evelevation do to heat or exercise. (Merocrine sweat glands) (1 space)
22. - specialized epithelial cells that produce sebum (1 space)
23. -receptors which indicate the amount of pressure felt on skin; (Two types: light, heavy) (1 space)

1. -carry nutrients and oxygen to upper layer of skin; regulates body temperature (2 spaces)
2. - (nail plate, nail bed)
3. -pigment that produces skin color
4. bodily response to injury, infection, or stress. - Can signal immune cells such as macrophages, as well as repair cells to cite of inflamtion.
7. - accumulation of packed dead cells which are brought to top of epidermis where they are shed (1 space)
8. -attaches to each hair follicle; contracts during cold/emotionally destressed circumstances; contraction of which causes goosebumps in humans (2 spaces)
9. - layer beneath dermis (not a true layer of skin) (1 space)
10. -When the deep red tone of hemoglobin look blue under the skin
11. -uneven border between epidermis and dermis, creating a unique ridge pattern resembling a person’s fingerprint (1 space_
15. - stem cells which produce hair. (1 space)
16. - (brownish/blackish melanin)
18. - (redish - yellowish melanin)
21. - oily material/cell debris that keeps skin and hair soft and water proof
