Identify the INCORRECT statement
Epithelia are classified by the number of cell layers.
In pseudostratified epithelia, all epithelial cells are in contact with the basement
membrane.
Epithelia are classified by the shape of the cells in the basal cell layer.
The appearance of an epithelium can vary with the angle of the section relative to
the surface of the epithelium.
The rules that are used to classify epithelia can be used to describe endothelia and
mesothelia. - Correct Answers -Epithelia are classified by the shape of the cells in the
basal cell layer.
Identify the INCORRECT statement
Epithelia are avascular.
Microvilli increase the surface area of the epithelia cells.
The basement membrane can act as a selective filter between epithelium and
connective tissue.
Absorptive epithelia contain a dense network of blood vessels.
Cilia are actively motile structures, which help to move substances along the
epithelial surface. - Correct Answers -Absorptive epithelia contain a dense network of
blood vessels.
Identify the INCORRECT statement
Intercellular attachment (tight junction) between epithelial cells is an effective barrier to
the diffusion of substances across an epithelium.
Cilia are apical projections that can be seen easily with the light microscope.
Microvilli are barely visible with the light microscope
Epithelia are relying on nourishment from the capillaries of the underlying
connective tissues.
Only stratified epithelia contain two or more rows of cell nuclei. - Correct Answers -Only
stratified epithelia contain two or more rows of cell nuclei.
Epithelial type that play a protective function and is found lining the esophagus
Epithelial type that is associated with distensible organs (e.g. urinary bladder)
Epithelial type found lining small capillaries where it modulates diffusion
