Layers of the Skin
Correct order of skin layers from superficial to deep.
What is epidermis → dermis → hypodermis?
This is the primary function of the integumentary system.
What is protection?
These cells produce melanin to protect against UV radiation.
What are melanocytes?
This is the first phase of wound healing involving bleeding control.
What is the inflammatory (hemostasis) phase?
These injuries are caused by prolonged pressure and are preventable.
What are pressure injuries?
This outermost skin layer is avascular and protects against fluid loss.
What is the epidermis?
This function involves detecting pain, temperature, and pressure.
What is sensation?
Bluish discoloration of skin due to low oxygen levels.
What is cyanosis?
This phase includes granulation tissue formation and new blood vessels.
What is the proliferative phase?
This burn affects the dermis and causes blistering.
What is a second-degree burn?
This layer contains blood vessels, nerves, and collagen.
What is the dermis?
The skin produces this vitamin when exposed to sunlight.
What is Vitamin D?
Redness of the skin often due to inflammation.
What is erythema?
This final phase involves scar formation and strengthening.
What is the maturation phase?
This common condition is inflammation caused by irritants or allergens.
What is dermatitis?
This layer provides insulation.
What is the hypodermis (subcutaneous layer)?
The skin helps regulate temperature through these two mechanisms.
What are sweating and vasodilation/vasoconstriction?
These immune cells recognize pathogens in the skin.
What are Langerhans cells?
his skin cancer is identified using the ABCDE rule.
What is melanoma?
This epidermal layer is responsible for mitosis and contains melanocytes.
What is the stratum basale?
This function prevents excessive water loss and dehydration.
What is fluid balance/retention?
These cells are responsible for light touch sensation.
What are Merkel cells?
This factor (low oxygen delivery) delays wound healing.
What is poor perfusion?
