the outermost layer of the epidermis consisting of dead cells that slough off..its the toughest layer of the epidermis
Stratum Lucidum (Epidermis Layers)
the layer of epidermis immediately under the stratum corneum in the skin of the palms and soles
Stratum Granulosum (Epidermis Layers)
the layer of epidermis just under the stratum corneum or (on the palms and soles) just under the stratum lucidum
Stratum Spinosum (Epidermis Layers)
The next layer up and is sometimes considered to be part of the stratum germinativum. , the spiny sublayer just below the stratum ganulosum contains cells that create an immune response to protect the body against foreign bodies that get through the first three outer sublayers of skin

What are the seven basic functions of the skin
sensation, Hydration, Absorption, Regulation,Protection, Excretion, Respiration
Sweat gland, has three functions.... control body temp, excretion of waste products, maintain the acidic pH factor of the skin
oil glands,when glands produce an over-abundance of sebum, the result is oily skin..
