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
