outermost layer of the skin, thinnest layer, contains no blood vessels, but has many nerve endings

 

epidermis

 
5. 

deepest layer of the epidermis, produces new epidermal skin cells

 

basal cell layer or stratum germinativium

 
6. 

cells that produce melanin, a dark skin pigment, that protects the sensitive cells in the dermis below from UV rays

 

melanocytes

 
7. 

the spiny layer just above the basal cell layer

 

stratum spinosum

 
8. 

granular layer, almost dead cells that are pushed to the surface

 

stratum granulosum

 
9. 

clear, transparent layer of epidermis just under the skin surface

 

stratum lucidum

 
10. 

the horny layer, outer layer of the epidermis, waterproof

 

stratum corneum

 
11. 

the underlying or inner layer of the skin, is about 25 times thicker than the epidermis, contains blood vessels, lymph vessels, nerves, sweat glands, oil glands, and hair follicles

 

dermis
