Skin and Body Membranes Review

epithelial membrane, connective tissue membrane
the two types of membrane
cutaneous membrane, mucous membrane, serous membrane
the three types of epithelial membrane
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
serous membrane inside the abdominopelvic cavity which surrounds the liver
serous membrane around the lungs
serous membrane around the heart
peritoneum, pleura, pericardium
the three types of serous membrane
layer of serous membrane closest to the organ it surrounds
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
skin is also known as the _____ system
37 degrees
body temperature in Celsius
drying up
outermost layer of the skin
middle layer of the skin
innermost layer of the skin
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
most keratinized layer of skin
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
produce melanin
interstitial fluid
tissue fluid
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
blood vessels _____ to cool off the body
blood vessels _____ to retain heat in the body
blood vessels increase diameter
blood vessels decrease diameter
melanin, carotene, hemoglobin
the three pigments which give skin its color
pigment produced by melanocytes
pigment whose produced amount is dependent on genetics and exposure to sunlight
pigment which gives a pinkish hue to the skin
ducts which secrete substances to the outside of the body
sebaceous, sweat
the two types of cutaneous glands
sebaceous glands
glands which secrete 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

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
