25
how many layers of stratum corneum
15-30 layers
26
statum lucidum is only seen in
thick skin
27
most superficial layer of epidermis is the
stratum corneum
28
below epidermis is
dermis
29
dermis is what type of tissue
connective
30
dermis tissue components
leukocytes, fibroblasts, wbc
31
if you bleed in cut you hit
dermis layer
32
dermis papillary layer is
areolar ct with collagen, and elastic fibers
33
paillary layer of dermis has
dermal papillae to help make fingerprints pattern
34
below papillary layer is
reticular layer
35
reticular layer is
dense irregular ct with adipose cells and thick collagen fibers
36
below dermis is
hypodermis
37
according to textbook the hypodermis
is not part of skin
38
hypodermis anchors
skin to underlying structures
39
hair is
dead keratinized cells
40
the root of the hair is located
in hair follicule
41
at base of hair root
goes into swollen region for hair bulb
42
hair papilla is
blood vessels to provide to the hair
43
hair matrix
does cell divison to get more hair, pushes old cells upward
44
arrector pili muscle
causes goose bumps, help insolate
45
average scalp hair
100,000
46
vellus hair is
peach fuzz, babies all of em
47
2/3 of women hair is
vellus
48
90% of mens hair is
terminal hair
49
hair growth is fueled by
hormones and testosterone
50
what secretes sebum oil
sebaceous glands
51
what type of gland is sebaceous glands
holocine gland
52
sebum prevents hair
water loss
53
sebaceous follicles are on
face, back, chest, nipples, and external genitalia
54
cells in sweat glands
myoepithelial cells
55

60
what is below the nail body
nail bed
61
nail root is the coninuation of
nail body
62
nail root covers up
nail matrix
63
nail matrix pushes body outward
causes growth

69
which skin cancer is the least malignant
basal cell carcinoma
70
what causes basale cell carcinoma
proliferation of cells in stratum basale
71
squamous cell carcinoma arise from
keratinocytes in stratum spinosum
72
malignant melanoma is cancer of
melanocytes
73
