,1. Epidermis: Outermost layer of the skin and the thinnest of the laters
Despite lack of blood supply, it has the ability to regenerate every 4-6 weeks
2. 5 Layers of Epidermis: Stratum Corneum
Stratum Lucidum
Stratum Granulosum
Stratum Spinosum
Stratum Germinativum/Basale
3. Stratum Corneum: Made up of flattened dead cells
Can be seen being removed with bathing or rubbing
Important for providing protection from outside dangers and regulation of
fluids and electrolytes
4. Stratum Lucidum, Stratum Granulosum, Stratum Spinosum: Middle three
layers
Help in the reduction of friction and shear (skin pulled in one direction while
underlying tissue moves in opposite direction)
5. Stratum Germinativum/ Basal: Very active single layer of cells
,Constantly produces new cells that are pushed upward through the other
layers
6. Dermis: Layers between the epidermis and the deeper subcutaneous later
Much thicker than epidermis (thickness varies depending on part of body)
Irregular, interconnected projections link with the epidermis above
Connective tissue with its elastin and collagen fibers,
provides strength and elasticity Provides necessary oxygen
and blood
Contains sebaceous glands, sweat glands, hair, nail follicles, nerves, and
lymphatics
7. Rete Ridges or Papillary Dermis: Provide the "stick" that anchors these
layers of the skin together, preventing them from sliding back and forth
8. Subcutaneous Layer: Layer of adipose tissue, or fat
Attaches to the dermis to the underlying muscles and bone
Delivers the blood supply to the dermis
Provides insulation and cushioning
, Size varies depending on the body location and person's weight, sex, and age
9. Factors Affecting Skin Integrity: Wounds
Vascular Disease
Diabetes
Malnutrition
Age
10. Medical Adhesive-Related Skin Injuries (MARSIs): When superficial layers
of skin are removed by medical adhesive
11. Wound Classification: Skin Integrity
Wound Depth
Amount of Contamination
Healing Process
12. Skin Integrity: Open wound
Closed wound
13. Open Wound: An actual break in the skin's surface
Ex: Abrasion, puncture wound, and a surgical incision
