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
