How can you tell a pseudostratified columnar epithelium from a simple columnar epithelium or stratified columnar epithelium?
Look at the basal surface.
Look at the apical surface.
Check if its ciliated or not.
Look at the nuclei.
You are looking at a stratified epithelium and you notice that the cell shape at the basal surface is different than the cell shape at the apical surface. How do you name this epithelium?
Use the cell shape at the apical surface.
Use the cell shape at the basal surface.
Look in the middle and use that cell shape.
This will never happen.
What type of epithelium?
Non-Ciliated pseudostratified columnar epithelium.
Ciliated pseudostratified columnar epithelium.
Simple squamous epithelium
Stratified squamous epithelium.
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 the choices are correct.
Which of the following is NOT a true statement about epithelial tissue?
Epithelial tissue is vascular.
Epithelial tissue provides physical protection for organs.
Epithelial tissue functions in absorption and secretion.
Epithelial tissue controls the permeability into and out of an area or 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 any blood vessel.
All of the choices are correct.
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.
Epithelial cells that appear cube-like when an organ is relaxed, and flattened when the organ is distended by fluid, are classified as
simple columnar epithelium.
pseudostratified epithelium.
stratified squamous epithelium.
transitional epithelium.
simple squamous epithelium.
Connective tissue
joins together cells and tissues and transports substances.
provides a supporting framework for the body.
is characterized by large amounts of extracellular matrix.
Both "joins together cells and tissues and transports substances" and "is characterized by large amounts of extracellular matrix
All of the choices are correct.
