Flashcards in chapter 5 - tissues Deck (40):
that tissue which conducts the specific function of the organ and which usually comprises the bulk of the organ
supports the parenchyma; comprises everything else (connective tissues, blood vessels, nerves, ducts)
anchors epithelium to underlying connective tissue
single layer of thin, flattened cells through which substances pass easily (gas exchange, filtration)
simple squamous epithelium
Where are simple squamous located?
Single layer of cube-shaped cells; carries on secretion and absorption functions
Where is simple cuboidal located?
Kidney tubules and ducts
Single later of elongated cells whose uncle are near the basement membrane; contains goblet cells that secrete mucus; have microvilli on top
Where is simple columnar located?
Lines the uterus and portions of the digestive tract (small intestine, large intestine, and stomach)
appears stratified, where nuclei are at two or more levels, cilia is present on apical surface
Where are pseudostratifed columnar located?
Line the respiratory passages
composed of many layers of cells, top layers are flattened, where they protect underlying cells from harmful environmental effects
Where is stratified squamous located?
Superficial portion of skin, oral, vaginal, and anal cavities
composed of two or three layers of cube-shaped cells; important for containment
Where is stratified cuboidal located?
Lines the ducts of mammary glands, sweat glands, salivary glands, pancreas
two layers of elongated cells, not ciliated
Where is stratified columnar located?
ONLY in urethra
specialized to stretch, change in response to increased tension
Where is transitional epithelium located?
Forms the inner lining of the urinary bladder and lines the ureters and superior urethra
Composed of cells specialized to produce and secrete substances into ducts or into body fluids; usually found within columnar or cuboidal epithelium
Composed of simple cuboidal cells
secrete watery fluids without the loss of cytoplasm (exocytosis)
lose portions of their cells during secretion; mammary glands
release cells filled with secretions (hair)
intestinal glands of small intestine
sweat glands of the skin
simple coiled tubular
bulbourethral glands of males
simple branched tubular
sebaceous glands of skin
simple branched alveolar
LOOSE, forms thin membranes between organs and binds them, thick and thin fibers are present with lots of space
loose areolar connective tissue
Where is loose areolar tissue located?
In the calves
stains light, nuclei are pushed off to the side; stores fat, cushions, and insulates
Where are adipose tissue located?
Everywhere, around hair follicle
stains dark, lots of dark spots and hair like fibers
Where is reticular tissue located?
Only in the liver
WAVY, closely packed = STRONG; largely composed of strong,collagen fibers that bind structures; lousy blood supply
dense regular connective tissue
Where is dense regular tissue located?
Tendons and ligaments
thin hairs intermixed with collagenous fibers
elastic connective tissue
