Document Summary
Physci 400 week 3 lect 1 part 1. 5. 6 describe the processes that produce hair and the structural basis for hair texture and color. 5. 7 discuss the various kinds of glands in the skin, and list the secretions of those glands. 5. 8 describe the anatomical structure of nails, and explain how they are formed. 5. 9 explain how the skin responds to injury and repairs itself. 5. 10 summarize the effects of aging on the skin. The integumentary system (introduction: two major parts of the integumentary system (or integument, cutaneous membrane, or skin. Accessory structures: hair, exocrine glands, nails, proteoglycan: part protein and sugar. Stitches cells together: hemidesmosomes: attach a cell to extracellular structures(3 and 4 are structure giving functions) (not the strongest of the function) If desomosomes fell on one layer, then the skin could be compromised. Blister liquid will stay on the body until cell regeneration is activated or the blister is popped.
