Flashcards in Skin Structure and Function Deck (17):
1

What is glabrous skin?

Smooth skin (hairless)

2

What is unique to the epithelium?

It has a basement membrane and no blood vessels or nerves pass through the basement membrane

3

What are the layers of skin from deep to superficial?

Stratum basale
Stratum spinosum
Stratum granulosum
Stratum lucidum
Stratum corneum

4

What distinguishes the stratum basale?

Mitotically active cells
One cell thick
Has melanin

5

What distinguishes the stratum spinosum?

Spiny processes
Multiple layers thick
Doesn't stain well

6

What distinguishes the stratum granulosum?

Produces products used in the water barrier
Tightly packed
Stains dark because of granules

7

What distinguishes the stratum lucidum?

It is found only in thick skin
Subdivision of stratum corneum

8

What distinguishes the stratum corneum?

Keratinized cells

9

Mnemonic for remembering layers of epithelium

Come Let's Get Sun Burned

10

Where are apocrine glands found?

Axilla, genitals, anus

11

Where are eccrine glands found?

Everywhere that apocrine glands are not found

12

Where are sebaceous glands found?

In non-glabrous skin

13

What creates the water barrier in skin?

Tonofibrils combined with keratohyalin within cell cytoplasm which then form the cell envelope

14

Where is tonofibril synthesized?

Stratum basale cells

15

Where is keratohyalin created?

Stratum granulosum

16

What is indicated if melanin is found in the dermis?

Typically means abnormal growth and division

17

What are the letters in the ABCD rule?

Asymmetrical shape of skin lesion
Border of the lesion is irregular
Color variations (melanomas have multiple colors)
Diameter of skin lesions (greater than 6 mm suspicious)
