STUDY
PLAY
epithelial membrane, connective tissue membrane
the two types of membrane
cutaneous membrane, mucous membrane, serous membrane
the three types of epithelial membrane
skin
cutaneous membrane is also known as the _____.
mucous membrane
membrane that lines all body cavities that open to the exterior body surface
mucous membrane
membrane that lines the respiratory tract, urinary system
serous membrane
membrane that lines all open body cavities
stratified squamous epithelium, simple columnar epithelium
makes up mucous membrane
simple squamous epithelium
makes up serous membrane
serous membrane
separates organs from each other and from body cavity
serous membrane
reduces friction between organs
serous fluid
substance between serous layer
peritoneum
serous membrane inside the abdominopelvic cavity which surrounds the liver
pleura
serous membrane around the lungs
pericardium
serous membrane around the heart
peritoneum, pleura, pericardium
the three types of serous membrane
visceral
layer of serous membrane closest to the organ it surrounds
parietal
layer of serous membrane which forms outside layer
visceral pericardium
layer of serous membrane closest to the heart
parietal peritoneum
outside layer of serous membrane surrounding the liver
visceral pleura
layer of serous membrane closest to the lungs
synovial membrane
example of connective tissue membrane
synovial membrane
membrane which lines fibrous capsules surrounding joints
integumentary
skin is also known as the _____ system
37 degrees
body temperature in Celsius
desiccation
drying up
epidermis
outermost layer of the skin
dermis
middle layer of the skin
hypodermis
innermost layer of the skin
hypodermis
not a true part of the skin, mostly adipose tissue. serves as an insulator and shock absorber.
stratified squamous epithelium
epithelium which makes up the epidermis
epidermis
most keratinized layer of skin
keratin
type of protein which hardens the skin
stratum corneum
most superficial layer of epidermis
stratum basale
most deep layer of epidermis
stratum corneum
strata which makes up 3/4 of epidermis
stratum corneum
strata which is mostly made of dead, keratinized cells and protects deeper living cells from damage
stratum basale
strata made mostly of living cells which undergo cell division and push dead cells to the surface of the skin
stratum basale
strata which contains melanocytes
melanocytes
produce melanin
interstitial fluid
tissue fluid
dermis
layer of skin made of dense fibrous connective tissue
papillary, reticular
the two layers of the dermis
papillary layer
most superficial layer of dermis
reticular layer
most deep layer of dermis
papillary layer
layer of skin which contains dermal papillae
papillary layer
contains blood vessels, capillary loops, pain receptors, touch receptors, nerve receptors, collagen, and elastic fibers
papillary layer
layer of skin which contains Meissner's corpuscles
Meissner's corpuscles
touch receptors
reticular layer
contains blood vessels, sweat and oil glands, deep pressure receptors, nerve receptors, phagocytes, collagen, and elastic fibers
reticular layer
layer of skin which contains pacinian corpuscles
pacinian corpuscles
deep pressure receptors
prevent bacteria that enter skin from entering deeper tissue
function of phagocytes in the dermis
reticular layer
layer of skin which contains phagocytes
reticular layer
layer of dermis which contains sweat and oil glands
dilate
blood vessels _____ to cool off the body
constrict
blood vessels _____ to retain heat in the body
dilate
blood vessels increase diameter
constrict
blood vessels decrease diameter
melanin, carotene, hemoglobin
the three pigments which give skin its color
melanin
pigment produced by melanocytes
melanin
pigment whose produced amount is dependent on genetics and exposure to sunlight
hemoglobin
pigment which gives a pinkish hue to the skin
exocrine
ducts which secrete substances to the outside of the body
sebaceous, sweat
the two types of cutaneous glands
sebaceous glands
glands which secrete sebum
sebum
substance which is a combination of oil, fragmented cells, and chemicals. antibacterial and lubricates skin.
sebaceous glands, apocrine sweat glands
glands which are activated at puberty
eccrine, apocrine
two types of sweat glands
eccrine sweat glands
type of sweat glands involved in heat regulation
eccrine sweat glands
major type of sweat glands, found throughout the skin
apocrine sweat glands
sweat glands found in genital and axillary regions
sweat glands
function is to dissipate excess heat, excrete waste products, prevent bacterial growth
sun
hair is pigmented as protection from _____.
cuticle
outermost layer of hair
cortex
middle layer of hair
medulla
innermost layer of hair
cuticle
most heavily keratinized layer of hair
hair follicle
"live" part of hair
arrector pili
smooth muscle which contracts to make hair stand on end
sebum
substance which keeps hair soft and shiny
nails
heavily keratinized, non-pigmented scale-like modifications of the epidermis
fungus
cause of athlete's foot
bacteria
cause of boils
bacteria
cause of carbuncles
bacteria
cause of impetigo
virus
cause of cold sores
psoriasis, eczema
skin homeostatic imbalances with unknown causes
the extent of burns
rule of nines determines _____.
first degree burn
burn where only epidermis is damaged
first degree burn
burn where skin is red and swollen
second degree burn
burn where epidermis and upper dermis are damaged
second degree burn
burn characterized by redness and blisters
third degree burn
burn where entire skin layer is destroyed
dehydration, infection, electrolyte imbalance, circulation shock
associated dangers of burns
rule of nines
way to determine the severity of burns. body is divided into 11 sections for quick estimation; each area represents about 9%
third degree burn
burn where skin becomes gray-white or black
third degree burn
burn which requires skin graft
benign
abnormal cell mass which does not spread
malignant
abnormal cell mass which metastasizes to other parts of the body
metastasize
to spread (cancers)
basal cell carcinoma
least malignant skin cancer
basal cell carcinoma
most common skin cancer
squamous cell carcinoma
skin cancer which metastasizes to lymph nodes. early action gives good chance of cure
malignant melanoma
most deadly skin cancer
malignant melanoma
cancer of melanocytes
malignant melanoma
