covering and lining membranes
epithelial membranes
t/f: epithelial membranes contain epithelial layer only
false, it has an underlying layer of connective tissue
cutaneous membranes are composed of
superficial epidermis and dermis
epidermis is composed of
stratified squamous
t/f: dermis is composed of dense regular connective tissue
false, dense irregular
t/f: cutaneous are moist membranes
false, dry membranes
lines all the body cavity open to the exterior
mucous membranes
it is the epithelium resting on a loose areolar tissue
lamina propria
mucous membranes contains what kind of tissues within the mouth and esophagus?
stratified squamous
mucous membranes contains what kind of tissues within the digestive tract
simple columnar
function of mucous mem
absorption or secretion
t/f: urinary tract secrete large amounts of protective lubricating mucous
false, it does not
line compartments in the ventral cavity that are closed to the exterior
serous membrane
t/f: serous membrane contains stratified squamous epithelium
false, simple squamous
t/f: serous mem occur in pairs
true
sinong cute?
lala
lines a specific portion of the wall of the ventral cavity
parietal layer
covers the outside of the organs in that cavity
visceral cavity
t/f: the serous layers are separated by air
false, serous fluid
peritoneum
abdominal cavity
pleurae
lungs
sinong love mo?
si Lord
pericardia
heart
contains only areolar tissue and no epithelial cells
synovial membranes
lines the fibrous capsules surrounding joints
synovial membranes
t/f: synovial mem provide a smooth surface and secrete lubricating fluids
true
has relatively impermeable keratinized cells which alert the nervous system for possible damage
skin protects from mechanical damage
protects DNA from UV damage
skin protects from UV radiation
morse type: a.) skin contains a water-resistant glycolipid b.) skin contains keratin
both true
the capillary network of the skin and sweat glands are both controlled by
nervous system
what do we call when the skin produce acid secretions
acid mantle
the acid mantle is responsible for?
protect against bacterial invasion
morse type: a.) the skin manufactures proteins important to immunity b.) it synthesizes vitmain C from cholesterol
true, false: vitamin D
t/f: the epidermis is tear resistant
false, dermis
what is below the dermis
subcutaneous tissue or hypodermis
subcutaneous is composed of what tissue
adipose
subcutaneous tissue serves as a
shock absorber
function of subcutaneous
insulates the deeper tissues from extreme temp changes
provides a site for nutrient storage in the skin
subcutaneous tissue
fibrous protein that makes the dermis a tough protective layer in a process
keratinization
t/f: epidermis is vascular
false, epidermis has no blood supply
the deepest cell layer of the epidermis
stratum basale
stem cells in this layer are constantly dividing
stratum basale
alternate name of stratum basale
stratum germinativum
t/f: the daughter cells from the stratum basale are pushed upwards
true
the cells contain thick bundles of filaments made of pre-keratin after being in stratum germinativum
stratum spinosum
cells starts to deteriorate, and the cytoplasm is full of granules
stratum granulosum
this epidermal layer occurs when the skin is hairless and extra thick
stratum lucidum
cells begin to die
stratum lucidum
examples of stratum lucidum
palms & soles
20-30 layers thick and accounts for the three counters of epidermal thicknes
stratum corneum
ano ang epidermal layer ang may horny cells
stratum corneum
pigment that ranges in color from yellow to brown
melanin
spider shaped cells that produce melanin
melanocytes
where can we find melanocyctes
stratum basale
it is seen where melanin is concentrated in one spot
freckles and moles
they alert and activate the immune system to threat a invasion
epidermal DENTRIC cells
what do we call the touch receptors within the epidermal junction
merkel discs
associated with sensory nerve endings
merkel cells
strong stretchy envelope that help bind the body togetger
dermis
region in the dermis that contains areolar tissue
papillary
reticular region in the dermis contains
dense irregular
morse: function of papillary layer is to a.) furnish nutrients to the epidermis, b.) increase friction and enhance grippping
both true
t/f: papillary patterns are genetically determined
true
the blood vessels, sweat and oil glands and the deep pressure receptors are called the
lamellar corpuscles
function of collagen fibers in the dermis
toughness of the dermis
t/f: collagen fibers attract and bind water to help the skin be hydrated
true
t/f: as we age, we gain more elastic tissues
false, it decreases therefore causing wrinkles
t/f: people with fair skin have more melanin than people with dark skin
false, more melanin the darker your skin color is
the skin tends to have a yellow orange cast because of
carotene
t/f: not all cutaneous glands are exocrine glands
false
t/f: cutaneous glands are pushed deeper into the skin
true
product of sebaceous glands
sebum
contains chemicals that kill bacteria so it is important in preventing bacterial infection of the skin
sebum
t/f: the sebum maintains the brittleness of the skin
false, it is a lubricant to keep the skin soft and moist
2 types of sweat glands
eccrine and apocrine
morse type: a.) eccrine glands produce sweat and water with salts b.) eccrine glands produce vit c, and lactic acid
both true
function of eccrine glands
body’s heat regulating equipments
confined to the axillary and genital areas
apocrine glands
the part of the hair enclosed in the hair follicle
root

b Nyey mali ka noh
the hair is made up of
medulla, cortex, cuticle
most keratinized region sa hair
cuticle
responsible for nail growth
nail matrix
it is where the stratum basale of the epidermis extended beneath the nail
nail bed
yes or no: pag naputulan ka ng kamay tas naputol ung buong kuko plus nail matrix tutubo pa ba yon?

most common skin disorders
infections with pathogens
abnormally strong immune responses
allergies
3rd degree burn destroy what
epidermis, dermis and subcutaneous tissue
most common skin cancer
basal cell carcinoma
cancer of the melanocytes
malignant melanoma
