25
2 layers of dermis
papillary recticular
26
made of loose tissue and fibers that allow phagocytes to patrol for microorganisms-areolar connective tissue
dermal papillae
27
on thick ski such as palms and finger tips papillea form ridges that provide friction for grasping
friction ridges
28
deeper and thinker layer made of course dense fibrous connective tissue accounts for 80 % of dermis -irregular dense connective tissue
recticular dermis
29
this layer contains elastic fibers and collegen fibers - it has seperations less dense regions between bundles of fibers
recticular dermis
30
the seperation between the less dense regions between bundles of fibers in the reticular dermis
cleavage -tension lines
31
dermal folds that opccure at or near the joint visable on hands
flexure lines
32
3 pigments of skin tone
melanin carotene hemoglobin
33
only pigment made in skin ranges from reddish to yellow-brown black
melanin
34
all humans have same amount of melanocytes but amount produced differes accourding to genetic and enviromental factors-freckles and nevi
melinin
35
comes from food yellow to orange most obv in soles and palms
carotene
36
provides a pinkisk-red hue especially in fair skin from oxygen carried in blood
hemoglobin
37
bluye-low oxygen of hemoglobin
cynosis
38
redness-fever hypertension inflammation allergy
erythema
39
blanching, anemia, low bp fear anger
pallor
40
yellow liver disorder
jaundice
41
the accosery organs of the skin
hair nails hair follicles sweat and sebaceous glands
42
flexable strands of dead karatinized cells found on nearly allbody surfaces
hair-pili
43
hair-area that extends beyond the skins surface part you can see has no nerves kertinaztion complete
shaft
44
hair-portion below the skins surface you cant see surrounded by hair follicule kertinization still going
root
45
hair-small band of smooth muscle attached to hair follicle-responsible for goose bump
arrector pili
46
3 -hairs functions
protect agains heat loss protect agains trauma protect from sunlight
47
hair color
melanocytes
48
thin hair that covers the fetus disappears except for hair and eyebrows
lanugo
49
faint fine hair found on children and adult females
vellus
50
thicker courser hair found on scalp and pubic area
terminal
51
the uppermost portion of a hair follicle, starting at the skin's surface and extending to the opening of the sebaceous gland
infundibulum of the sebaceous gland
52
scalelike modifications of the epidermis that contains hard keratin
naail
53
the epidermis underneath the keratinized nail plate
the nail bed
54
skin folds that overlap border of nail
nail fold
55
nail fold that projects onto the surface of the nail body
cuticle-eponychium
56
area under free edge of plate that accumulates dirt
hyponychium
57
thickened yellow nails
fungal infection
58
outward concavity of nail may be signal iron deficiency
spoon nail-koilonchya
59
may indicate COPD poor oxygen profusion
clubbed nails
60
horizental lines across nails may indicate severe illness such as uncontrolled diabetes heart attack or cancer or chemo
beau lines
61
white cresent shape at base of nail
lunula
62
2 glands associated with skin
sudoriferous-sweat sebacous-oil
63
2 types of sudoriferous glands
eecrine apocrine
64
contract upon nervous system stimulation to force sweat into ducts thermoregulation-regulated by sympathetic nervous syetm
eecrine
65
found on axilla and external genetalia secrete viscous milky yellow sweat-contains fatty substances and protine functions at puberty
apocrine
66
modified appocrine glands-sweat glands
ceruminous mammory
67
secrets wax lines inner ear
ceruminous
68
found everywhere but especially palms soles and forhead secretes hypotonic filtrate of blood plasma secretes by exocytosis some bacterial properties
eecrine gland
69
sexual scent gland filtrate of blood plasma with protines and fatty substances excyotosis secretes at hair follicle
appocrine gland
70
know as holocrine glands associate with hair follicle, some onto skin secrete oil-sebum secretes by holocrine everywhere but palms and soles unactive until puberty abacterial
sebaceous glands
