Homeostatic Imbalances:Integumentary System
Stretch Marks
Tearing of the reticular layer of the dermis
Bed Sores
-Person lying in same position will prevent blood flow to dermis
-Consequences: Cells die and open wounds form
Rickets-Prolonged lack of exposure to sunlight = little vitamin D-Vitamin D- Helps regulate metabolism of phosphorus and calcium
Hirsutism
• Excessive body and facial hair
Neoplasms
-Growths on/in the skin
-Examples- warts, cysts, skin cancer
Burns/Frostbite
• Extreme temperatures have a drastic affect on integumentary system
• Kill stratum basale in extreme cases
Fixing Burns/Frostbite
• Skin Grafts– Taking epidermis from a donor site and putting it
in a damaged site.
Synthetic Skin
-Animal tissue bonded to silicon film
Scars
• Deep enough cuts cause stratum granulosum to become scar tissue
Aging
• Collagen fibers in dermis become hard and thick
• Adipose tissue in hypodermis diminishes– Makes skin thin
• Less Epithelial derivatives
