Chapter 4- Integumentary System Flashcards
The structure of the integumentary system is from superficial to Deep, it is made up of 3 layers?
- Epidermis
- Dermis
- Subcutaneous tissue (Ct to help maintain the cutaneous)
What are the functions of the Integumentary System ?
- Protection (barrier, cushioning, monitoring(sensory
nerves),UV) - Thermoregulation (constrict through the cold and dilates in the
heat) - Blood Reservoir- (8-10% of the blood is in the dermis)
- Excretion
- Vitamin Synthesis (helps with Vitamin D Synthesis and Calcium
Absorption)

Keratinocytes produce ——–?
keratin (cells are keratinized)
Keratinocytes deeper cells constantly ———-?
- divide ( as a protection)
There 5 layers to the epidermal layer ;
1———-2———3———–4 ———-5———–?
- Stratum basale
- Stratum Spinousum
- Stratum Granulosum
- Stratum Lucidum
- Stratum Corneum
————–flat, dead keratinocytes that are shed.
Stratum Corneum
—————flat, dead keratinocytes
Stratum Lucidum
———–cells that are dying
Stratum Granulosum
Stratum———provides ———and ————to the skin
