Chapter 4 Integumentary System Flashcards
Integumentary system
skin and associated structures (glands, hair, nails)
function of integumentary system
protects against
UV radiation
dehydration
injury
infection
temp regulation
touch pressure pain
derma
skin
cutaneous
skin (latin word cutis)
epidermis
outermost layer of skin, made of epithelial cells
keratin
a protein that thickens and toughens the skin
melanin
gives skin color and protects against sun
eponychium
nail
sweat glands
watery fluid, temperature regulations
sebaceous glands
oil- lubricates hair and skin and prevents drying (associated with hair follicle)
dermis
skin between epidermis and subcutaneous
hair follicle
sheath in which hair develops
derm/o, dermat/o
skin
kerat/o
keratin, horny layer of skin
melan/o
dark, black, melanin
hidr/o
sweat, perspiration
seb/o
sebum, sebaceous gland
trich/o
hair
onych/o
nail
sebum
fatty secretion of the sebaceous glands that lubricates the hair and skin
skin
tissue that covers the body; the integument
subcutaneous layer
beneath the skin
also hypodermis
sudoriferous glands
sweat glands
eccrine glands
found all over body, highest in palms and soles
cooling down
apocrine glands
armpits and perineal area, pheromones
bulla
raised, fluid filled lesion
BLISTER
larger than a vesicle
fissure
crack or break in skin
mascule
flat, colored spot
- less than 1 cm in size
nodule
solid, raised lesion
- larger than papule
- systemic disease
papule
firm, circular, raised lesion
- small (less than 1 cm)
- pimple
plaque
superficial, flat, slightly raised differentiated patch more than 1 cm in diameter
pustule
raised pus-filled lesion
many times in pore or hair follicle
ulcer
lesion from destruction of skin/subcu tissue
vesicle
fluid filled raised lesion less than 5mm
- blister/bleb
wheal
smooth, rounded, slightly raised
- itchy
- HIVES
dehiscence
disruption of wound layers
evisceration
internal organs go through lesion
exudate
cells drain from damaged tissue
- clear
- bloody
- pus-containing
cicatrization
sik-ah-trih-ZA-shun
scar
keloid
excess collagen formation during healing
- asian/african
debridement
removal of dead or damaged tissue
- cut
-scrubbing
escharotomy
scab removal of thick, dark crust
dermatome
skin grafting tool
thin sections of skin
superficial burn
only epidermis
- red and dry
- minimal pain
-blanching (whitening then turning back red with pressure)
superficial partial thickness
epidermis and superficial dermis
- red
- painful
-blister
deep partial thickness
epidermis and full dermis
- weeping surface
-dry (sweat gland damage)
- nerve damage
-blood
full thickness
all the way to subcu and deeper
- charred
-loss of limbs
- skin grafting
BSA
body surface area
rule of nines
for burn BSA (body surface area)
- body surfaces measured in percentages in multiples on nines
burn complications
infection
respiratory
shock
pressure ulcers
necrotic skin from pressure on bony projections
- decubitus ulcer
- bedsore
dermatitis
inflammation of skin
- erythema
- pruritis
