Tissue Flashcards
have a free surface exposed to the outside, to a body cavity or lining of an internal organ
Epithelial tissue
usually function for
secretion & absorption
cuboidal epithelium
may have microvilli or cilia on free surface
columnar epithelium
found in organs that can stretch
transitional epithelium
air sacs/alveoli (lungs),
capillaries, glomeruli (kidneys)
simple squamous epithelium
kidney tubules, ducts of thyroid gland & pancreas
simple cuboidal epithelium
single layer of tall cells;
may contain goblet cells that
secrete mucus &/or microvilli
simple columnal non-ciliated epithelium
lining of stomach & intestines
simple columnar non-ciliated epithelium
single layer of tall cells w/ cilia; may contain goblet cells
single columnar ciliated epithelium
lining of upper respiratory tract & uterine/fallopian tubes
single columnar ciliated epithelium
appears stratified (nuclei at various levels); may contain
goblet cells
Pseudostratified columnar epithelium
multiple layers of cells w/ flat, keratinized/“dead” surface cells
Stratified Squamous Keratinized epithelium
multiple layers of cells w/ flat, non-keratinized/“living” surface
cells
Stratified squamous non-keratinized epithelium
lining of “wet” surfaces (mouth, vagina)
stratified squamous non-keratinized epithelium
if a transitional epithelium is stretched it is
squamous
if transitional epithelium is not stretched it is
columnar
lining of urinary bladder & ureters
transitional epithelium
secrete various substances (enzymes, hormones, perspiration, milk, saliva, mucus, etc.)
glandular epithelium
have ducts (tubes) that take secretions away from the gland to the site of its functio
exocrine
ductless
secrete hormones released into capillaries where blood brings it from the gland to the site of its function
endocrine glands
matrix of blood
plasma
enables transport of substances & gases
blood
protein fiber-producing cells
fibroblasts
what is the matrix of areolar connective tissue
collagen fibers and elastic fibers
release inflammatory chemicals
mast cells
provides strength, elasticity, & support
areolar connective tissue
fat-storing cells
adipocytes
what is the matrix of adipose tissue
little
thermal insulation, provide energy reserve, cushioning
adipose tissue
provides strong attachments
• location: tendons; ligaments
fibrous (regular)
provides strength
• location: dermis of skin; fascia around muscles
fibrous (irreg)
allows stretching of various organs
• location: arterial walls
elastic tissue
provides mechanical support; calcium & phosphate storage;
blood cell productio
bones
provides smooth surface for movement; provide support
• location: wall of trachea; joint surfaces of bones; tip of nose & outer ear;
between vertebrae
cartilage
striated
long, cylindrical
several nuclei per cell (peripherally-
located)
voluntary
skeletal muscle
striated
cylindrical, branched
single nucleus per cell (centrally-
located)
connected by intercalated discs
involuntary
cardiac muscle
not striated
spindle-shaped (tapered at each end)
single nucleus per cell (centrally-
located)
involuntary
Smooth muscle
sheets of tissue that cover or line surfaces or that separate organs or parts of organs from one another
membranes
what are the two epithelial membrane?
Serous and mucous membrane
mostly made up of simple squamous
epithelium
serous membrane
lines a body cavity that does not open directly to the outside
serous membrane
a serous membrane that covers the abdominal cavity
peritoneum
serous membrane that covers the
a. heart
b. lungs
a. pericardium
b. pleural
What are the two parts of serous membrane?
parietal and visceral
a serous membrane layer that is attached to the cavity wall
parietal
covers & attaches to the organs inside the cavity
visceral layer
lines a body cavity that opens directly to
the outside
mucous membrane
What do mucous membrane contain?
goblet cells
Mucous membrane can be found?
digestive tract
respiratory tract
urinary tract
reproductive tract
