Understanding tissue structure and function is important because:
There is a relationship between the structure of each tissue type (how it is organized) and its function (what it does).
There is a relationship between tissue structure and organ function.
Many diseases and pathologies are tissue and cell type specific.
Changes at the tissue level affect the function of organs.
All of these are correct.
Pick out the FALSE statement about epithelial tissue.
Epithelial tissue is vascular.
Epithelial tissue provides physical protection for organs.
Epithelial tissue functions in absorption & secretion.
Epithelial tissue controls the permeability into and out of an area/organ.
Epithelial tissue consists almost entirely of cells with very little extracellular material between them thereby forming a barrier against entry into the body.
Epithelial cells
cover body surfaces or form glands.
usually have a free surface that is not in contact with other cells.
have a basement membrane that attaches to underlying tissues.
can be somewhat far away from a blood vessel.
have all of these properties.
The most correct classification of an epithelial tissue consisting of many layers of cells, in which the outer layers are flat and thin, and the basal layers are cuboidal or columnar is
simple columnar epithelium.
pseudostratified epithelium.
stratified squamous epithelium.
transitional epithelium.
simple squamous epithelium.
Which of these epithelial types is correctly matched with its major function?
simple squamous epithelium - diffusion or filtration
stratified squamous epithelium - protection from abrasion
Simple cuboidal epithelium - active transport, facilitated diffusion, or secretion
Simple columnar epithelium - secretion or absorption
All these are correctly paired.
Cell connections that bind adjacent cells together and form permeability barriers are called:
tight junctions.
gap junctions.
desmosomes.
plasma junctions.
tonosomes.
In connective tissue, cells whose names contain the suffix - clast:
produce matrix
maintain the matrix
break down the matrix for remodeling
ingest foreign substances through phagocytosis
are non-motile cells that release histamines and other chemicals to promote inflammation.
Which of these connective tissue cells is NOT correctly matched with its function?
blast cells - make holes in extracellular matrix
clast cells - break down the extracellular matrix
cyte cells - maintain the extracellular matrix
mast cells - release chemicals promoting inflammation
macrophages - move about and ingest foreign substances
Which of the following fiber types is not correctly paired with its function?
collagen - flexible, resists stretching
reticular - forms a supporting network between cells
elastic - allows for consistent stretch and recoil
collagen - gives tissue its strength
All of these are correct.
The connective tissue that makes up the external ear is:
dense collagenous connective tissue.
hyaline cartilage.
fibrocartilage.
elastic cartilage.
loose or areolar connective tissue.
During tissue repair, the clot is first replaced by _____, a delicate connective tissue that consists of fibroblasts, collagen, and capillaries.
granulation tissue
phagocytic tissue
dense connective tissue
fibrin tissue
pus
Major components of the extracellular matrix of connective tissue include:
protein fibers, carbohydrates, and lipids.
phospholipids, glycoproteins, and proteins.
protein fibers, ground substance, and fluid.
ground substance, glycoproteins, and phospholipids.
ground substance, carbohydrates, and fluid.
The major symptoms of inflammation include:
redness and swelling
heat
pain
disturbance of function
All of these are symptoms of inflammation
In regeneration:
a new type of tissue develops causing the loss of some function.
new cells of a different tissue develop and normal function is restored.
new cells of the same type are created and normal function is usually restored.
the damaged cells repair themselves perfectly, restoring function.
viable cells are replaced by dead cells.
____________ covers ends of bones at joints.
Dense collagenous connective tissue
Hyaline cartilage
Fibrocartilage
Elastic cartilage
Loose or areolar connective tissue
The following are effects of aging in tissues EXCEPT:
Cell division is slower.
Red blood cell synthesis decreases.
Injury healing time is slower.
Collagen fibers decrease in number, yet become more flexible.
All of these are age related changes.
You would normally expect to find ____________________ in the outer layer of skin.
simple squamous epithelium
simple cuboidal epithelium
stratified squamous epithelium
transitional epithelium
simple columnar epithelium
You would normally expect to find ____________________ in the kidney tubules.
simple squamous epithelium
simple cuboidal epithelium
stratified squamous epithelium
transitional epithelium
simple columnar epithelium
Type of muscle tissue responsible for moving food through the digestive tract and emptying the urinary bladder.
cardiac muscle
skeletal muscle
smooth muscle
muscular system
Which of these is NOT one of the four basic tissue types?
glandular
connective
muscle
epithelium
nervous
