A

Dermatology

2
Q

Heat energy transmitted as rays to the surrounding area

A

Radiation

Ray-diation

3
Q

Heat energy passes by direct contact through a non-moving medium.

A

Conduction

4
Q

Convection

A

Heat transfer occurs in a gas or liquid by the circulation of currents from one region to another.

5
Q

As perspiration to other fluids on the skin and hair vaporize, they absorb heat.

A

Evaporation

Air currents can increase evaporative heat loss through convection

6
Q

What are the two principle layers of the skin?

A

Epidermis, dermis

7
Q

Uppermost layer of the epithelium

A

Epidermis

8
Q

The innermost layer of the epidermis

A

Stratum germinativum

(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.)

9
Q

What is the magic phrase you need to remember that lists the layers of the epidermis from deep to superficial?

A

Big stinky gorillas like corn

13
Q

What is another name for the stratum germinativum?

A

Basal layer

Think base/bottom. It’s the base of the epidermis.

14
Q

In which epidermal layer do cells rapidly multiply to compensate for the loss of skin cells on the corneum?

A

Stratum germinativum

The Big in big stinky gorillas like corn

15
Q

Stratum spinosim

A

Cells begin to shrink and draw apart

16
Q

What layer of the epidermis is thicker in body regions of rugged wear (ex: pawpads)?

A

Stratum spinosum

17
Q

In which epidermal layer does keratinization begin?

A

Stratum granulosum

Think of grains. The cell is beginning to harden
