The study of skin
Heat energy transmitted as rays to the surrounding area
Heat energy passes by direct contact through a non-moving medium.
Heat transfer occurs in a gas or liquid by the circulation of currents from one region to another.
As perspiration to other fluids on the skin and hair vaporize, they absorb heat.
Air currents can increase evaporative heat loss through convection
What are the two principle layers of the skin?
Uppermost layer of the epithelium
The innermost layer of the epidermis
(Think of germination. The stratum germinativum is where epithelial cells rapidly multiply to compensate for the loss of cells on the uppermost layer of the epidermis. The cells spread and develops just like a bunch of spores.)
What is the magic phrase you need to remember that lists the layers of the epidermis from deep to superficial?
Big stinky gorillas like corn
Basal, spinosum, granulosum, lucidum, corneum
Outer layer of skin
Thicker layer of the skin
Innermost layer of the epidermis
What is another name for the stratum germinativum?
Think base/bottom. It’s the base of the epidermis.
In which epidermal layer do cells rapidly multiply to compensate for the loss of skin cells on the corneum?
The Big in big stinky gorillas like corn
Cells begin to shrink and draw apart
What layer of the epidermis is thicker in body regions of rugged wear (ex: pawpads)?
In which epidermal layer does keratinization begin?
Think of grains. The cell is beginning to harden
