|
|
Describe the Stratum Basale |
- Cubodial - Simple - goes through mitosis every 19 days |
|
|
Describe the Stratum Spinosum |
- 8 to 10 layer thick - Lamellar (ability to feel pressure) - Special fat producing organelles |
|
|
Describe the Stratum Granulosm |
- Formation of keratin - Lamellar bodies - 2 to 5 layers - Has squamous layers going upward |
|
|
Describe the Stratum Lucidum |
- Dead cells - Full of keratin |
|
|
Describe the stratum Corneum |
- 25+ layers - Full of keratin - water resistant - Desmosome attachment begins to break down |
