Flashcards in Chapter 10 Deck (50):
1

Arrector pili muscle

Goosebump muscle

2

Barrier function

Acid mantle, protects skin

3

Ceramides

Natural part of skins intercellular matrix

4

Collagen

Fibrous connective tissue

5

Corneocytes

Dead skin cells

6

Dermal papillae

Attach to epidermis. Contains nerve endings and capillaries

7

Dermis

Support layer of connective tissue

8

Desmosomes

Assist in holding cells together. Made of proteins

9

Eccrine glands

Sweat glands found all over body

10

Elastin

Protein fiber found in dermis

11

Epidermal growth factor

Stimulates cells to reproduce

12

Epidermis

Outermost layer of skin. Has 5 layers

13

Eumelanin

Black melanin

14

Fibroblasts

Stimulating cells

15

Follicles

Pores

16

Glycation

Caused by elevation in blood sugar

17

Hair papillae

Supplies hair with nutrients

18

Hyaluronic acid

Holds 1000 times its weight in moisture

19

Hydrolipidic

Oil-water balance that protects skin

20

Intercellular matrix

Between skin cells to hold moisture

21

Keratin

Protein

22

Keratinocytes

Keratin cell

23

Langerhans immune cells

Guard cells

24

Leukocytes

White blood cells

25

Lymph vessels

Supplies skin with nourishment and removes waste

26

Melanin

Pigment

27

Melanocytes

Melanin making cells

28

Melanosomes

Melanin protein

29

Papillary layer

Top layer of dermis next to epidermis

30

Pheomelanin

Red or yellow in color. Mostly in light colored skin

31

Pores

Tube like openings

32

Reticular layer

Deeper layer of the dermis supplies skins w/O and nutrients

33

Rosacea

Condition where face looks flushed all the time

34

Sebaceous glands

Oil glands

35

Sebum

Oil in skin and hair that protects it

36

Stratum corneum

Horny layer

37

Stratum germinativum

Basal layer. Mitosis takes place here.

38

Stratum granulosum

Granual layer. Replaces she's cells from corneum

39

Stratum lucidum

Clear layer of epidermis. Thicker on palms of hands and bottom of feet

40

Stratum spinosum

Spiny layer. Just above basal layer. Contains Desmosomes

41

Subcutaneous layer

Hypodermis. Fat

42

Subcutis glands

Adipose tissue. Fatty tissue below dermis that creates contour

43

Sudoriferous glands

Sweat glands.

44

T-cells

Identify molecules that have foreign peptides and also help regulate immune response

45

Telangiectasia

Capillaries popping out

46

Transepidermal water loss

TEWL. water loss caused by evaporation on skin's surface

47

Tyrosinase

Enzyme that stimulates melanocytes and thus produces melanin

48

UVA rays

Aging Rays. The deepest and the weakest

49

UVB rays

Burning Rays.

50

Apocrine glands

Coiled structures attached to hair follicles found in the underarm and genital areas, secrete sweat
