Integumentary System

7. -attaches to each hair follicle; contracts during cold/emotionally destressed circumstances; contraction of which causes goosebumps in humans (2 spaces)
8. -Protien abundent in hair, nails)- helps structure/strength of skin/nails
9. -carry nutrients and oxygen to upper layer of skin; regulates body temperature (2 spaces)
10. -pigment that produces skin color
12. - Collagen, elastic fibers within gel-like extracellular matrix (1 space)
13. - stratified squamous (top layer) epithelium that lacks blood vessels
14. - oily material/cell debris that keeps skin and hair soft and water proof
16. -receptors which indicate the amount of pressure felt on skin; (Two types: light, heavy) (1 space)
18. -When the deep red tone of hemoglobin look blue under the skin
19. - (nail plate, nail bed)
22. - deepest layer of skin - place of cell division/growth (1 space)
23. -deepest part of hair follicle/root where epithelial stem cells lie (1 space)
24. -uneven border between epidermis and dermis, creating a unique ridge pattern resembling a person’s fingerprint (1 space_
25. -Half moon shaped part of nail, most actively growing region

1. - contain the melanosome organelle which produces melanin, the amount of which can effect the skin tone of a person.
2. - (redish - yellowish melanin)
3. bodily response to injury, infection, or stress. - Can signal immune cells such as macrophages, as well as repair cells to cite of inflamtion.
4. -Tube like depression of keratinized epithelial cells (1 space)
5. -As new cells form in bulb, the old cells are pushed outward and are caratonized forming a “” (1 space)
6. - accumulation of packed dead cells which are brought to top of epidermis where they are shed (1 space)
11. - specialized epithelial cells that produce sebum (1 space)
14. - layer beneath dermis (not a true layer of skin) (1 space)
15. inner layer (collagen, elastic fibers, smooth msucle tissue, nervous tissue, )
17. - (brownish/blackish melanin)
20. - stem cells which produce hair. (1 space)
21. - respond to temperature evelevation do to heat or exercise. (Merocrine sweat glands) (1 space)
