Correct Answer(s)
A. They have apical and basal poles and lateral surfaces as they are polarized
A. The apical pole might be cover by microvilli, stereocilia or cilia
A. The epithelial cells are always separated from the basement membrane
A. They have a lot of junctions with each other and with the basement membrane
A. The tissue is avascular
A. It has a good regenerationExplanation
The properties of epithelium include having apical and basal poles and lateral surfaces, which indicates that they are polarized. The apical pole may be covered by microvilli, stereocilia, or cilia. Epithelial cells are always separated from the basement membrane and have numerous junctions with each other and with the basement membrane. Epithelial tissue is avascular, meaning it lacks blood vessels. However, it has a good regeneration capacity, allowing it to repair and replace damaged cells.Rate this question:

The basement membrane is composed of one lamina
-
True, the basal lamina which have two parts lamina lucida and lamina densa
-
False, the basal lamina composed of two laminas the reticular lamina and the basal lamina which have the lamina lucida and the lamina densa.
Correct Answer
A. False, the basal lamina composed of two laminas the reticular lamina and the basal lamina which have the lamina lucida and the lamina densa.Explanation
The given answer is correct because the basement membrane is indeed composed of two laminas - the reticular lamina and the basal lamina. The basal lamina further consists of two parts, the lamina lucida and the lamina densa. Therefore, the statement that the basement membrane is composed of only one lamina is false.Rate this question:

What are the intercellular junctions of the epithelial cells?
-
Desmosome
-
Hemidesmosome
-
Adherent
-
Tight
-
Gap
Correct Answer(s)
A. Desmosome
A. Hemidesmosome
A. Adherent
A. Tight
A. GapExplanation
Intercellular junctions are specialized structures that connect epithelial cells together. Desmosomes are strong adhesive junctions that anchor cells together and provide mechanical strength. Hemidesmosomes are similar to desmosomes but connect cells to the extracellular matrix. Adherens junctions are important for cell-cell adhesion and are connected to the actin cytoskeleton. Tight junctions form a barrier between cells, preventing the passage of molecules between them. Gap junctions allow for direct communication and exchange of small molecules between cells. Therefore, the correct answer is desmosome, hemidesmosome, adherent, tight, gap.Rate this question:

The basement membrane of pseudostratified columnar ciliated epithelium is composed from:
-
Basal\cone shaped cells
-
Elongated cells
-
Columnar cells
-
Goblet cells
-
Simple squamous cells
Correct Answer(s)
A. Basal\cone shaped cells
A. Elongated cells
A. Columnar cells
A. Goblet cellsExplanation
The basement membrane of pseudostratified columnar ciliated epithelium is composed of basal/cone-shaped cells, elongated cells, columnar cells, and goblet cells. These different cell types work together to form the basement membrane, which provides support and structure to the epithelium. The basal/cone-shaped cells are located at the base of the epithelium and help anchor it to the underlying tissue. The elongated cells, columnar cells, and goblet cells make up the main body of the epithelium and are responsible for its function, including the secretion of mucus and the movement of cilia.Rate this question:

What are the functions of the basement membrane?
-
It supporting epithelial cells
-
It forms a barrier between epithelium and other tissues
-
It works as a filter which allowing only water, oxygen and small molecules or ions to pass
-
It provides nourishment to the cells
Correct Answer(s)
A. It supporting epithelial cells
A. It forms a barrier between epithelium and other tissues
A. It works as a filter which allowing only water, oxygen and small molecules or ions to passExplanation
The basement membrane has multiple functions. Firstly, it supports epithelial cells, providing them with a stable structure to attach to. Secondly, it forms a barrier between the epithelium and other tissues, preventing the migration of cells and maintaining tissue organization. Lastly, it acts as a filter, allowing only water, oxygen, and small molecules or ions to pass through, while restricting the passage of larger molecules and pathogens. Additionally, the basement membrane also plays a role in providing nourishment to the cells by facilitating the exchange of nutrients and waste products.Rate this question:

The epithelium of the vagina is stimulated by estrogen, they produce and accumulate glycogen. when the cells dies a bacteria convert the glycogen into lactic acid which in result lowers down the pH of the vagina
-
True
-
False
Correct Answer
A. TrueExplanation
The explanation for the given correct answer is that the epithelium of the vagina is indeed stimulated by estrogen, leading to the production and accumulation of glycogen. When these cells die, bacteria in the vagina convert the glycogen into lactic acid. This process lowers the pH of the vagina. Therefore, the statement is true.Rate this question:

In the surface layer of the basement membrane of the transitional cells there are specialized cells which are called umbrella cells
-
True
-
False, they lay in the basal layer
Correct Answer
A. TrueExplanation
The statement is true because in the surface layer of the basement membrane of the transitional cells, there are specialized cells called umbrella cells. These cells are named so because they have a unique shape that resembles an umbrella when viewed under a microscope. They play a crucial role in the urinary system by providing a protective barrier against the harmful substances present in urine, preventing them from damaging the underlying tissues.Rate this question:

Epithelial tissue originates from:
-
Ectoderm ( epidermis, sweat glands and mammary glands)
-
Mesoderm ( mesothelium and endothelium)
-
Endoderm (airway epithelium, thyroid, liver cells)
-
All of the above
Correct Answer
A. All of the aboveExplanation
Epithelial tissue originates from all three germ layers - ectoderm, mesoderm, and endoderm. The ectoderm gives rise to the epidermis, sweat glands, and mammary glands. The mesoderm is responsible for the formation of mesothelium and endothelium. The endoderm contributes to the development of airway epithelium, thyroid, and liver cells. Therefore, all of the given options are correct, as epithelial tissue can be derived from any of these germ layers.Rate this question:
