Integumentary System Flashcards
The outer epithelial
Epidermis
Outer most layer of epidermis, consisting layers of flat keratinized cells
Stratum cornrum
Outermost layer of skin. Cells continually shed and replaced by deeper layers
Keratin
Aka stratum germinativum. The deepest layer of epidermis composed of dividing stem cells
Stratum basale
Maintains and repairs tissues upon cell division
Stem cells
Produce melanin, an insoluble dark pigmentation
Melanocytes
Aka a mole. Caused by the growth of clustered melanocytes
Nevus
Connective tissue layer deep into the epidermis containing blood, lymphatic vessels, and nerves
Dermis
Aka oil glands. Cutaneous glands that secrete sebum

Furuncle
Aka integument, aka the skin
Cutaneous layer
Individual boils clustered together
Carbuncles
Causing follicular orifices to become prominent
Goosebumps
Causes goosebumps when contracted
Arrector pili mm
A burn to the outer most layer of the epidermis
First-degree burns
Burns damaging the underlying layers (stratum basale) causing a blister
Second-degree burn
A pocket of fluid collecting under damaged skin layer to protect further damages and allows to heal
Blister
A burn extending through all layers of skin into the bone and muscle layer
Third degree burns
A first degree burn and a second degree burn(up to 3 inches) are considered?
Minor burns
