What is letter "A" in the image of a simple squamous epithelial tissue?
-
Cytoplasm
-
Nucleus
-
Plasma/cell membrane
-
Rough Endoplasmic Reticulum
Correct Answer
A. NucleusExplanation
In the image of a simple squamous epithelial tissue, the letter "A" represents the nucleus. The nucleus is a membrane-bound organelle that contains the genetic material of the cell and controls its activities. It is typically located at the center of the cell and appears as a darkly stained structure. In this image, the letter "A" is likely pointing to a dark, round structure within the cell, indicating the presence of the nucleus.Rate this question:

-
Plasma/cell membrane
-
Rough Endoplasmic Reticulum
Correct Answer
A. Plasma/cell membraneExplanation
The letter "C" in the image of a simple squamous epithelial tissue represents the plasma/cell membrane. The plasma membrane is a thin, flexible barrier that surrounds the cell and separates it from its external environment. It regulates the movement of substances in and out of the cell, maintaining cellular homeostasis. In the context of a simple squamous epithelial tissue, the plasma membrane forms the outer boundary of the cells, allowing for the exchange of gases, nutrients, and waste products between the tissue and its surroundings.Rate this question:

Absorption and secretion
Correct Answer
A. Absorption and secretionExplanation
Simple columnar epithelial tissue is a type of tissue that consists of a single layer of tall, column-shaped cells. This type of tissue is found in areas of the body where absorption and secretion are important functions, such as the lining of the digestive tract. The tall, columnar shape of the cells allows for increased surface area, which enhances the tissue's ability to absorb nutrients and secrete substances. Therefore, the most correct function of simple columnar epithelial tissue is absorption and secretion.Rate this question:

This is a simple columnar ciliated epithelial tissue.
-
True
-
False
Correct Answer
A. FalseExplanation
The given statement is false. The description provided does not match that of a columnar ciliated epithelial tissue. Columnar ciliated epithelial tissue is a type of tissue found in the respiratory tract and fallopian tubes, characterized by tall, column-shaped cells with cilia on their surface. However, the statement does not provide any information about cilia or the specific location of the tissue. Therefore, the correct answer is false.Rate this question:

What is the classification of this epithelial tissue found in the bladder?
-
Simple Columnar Nonciliated
-
Simple Cuboidal
-
Transitional
-
Stratified Cuboidal
Correct Answer
A. TransitionalExplanation
Transitional epithelial tissue is the correct classification for the tissue found in the bladder. This type of tissue is specialized to stretch and accommodate changes in volume, which is important for the bladder's function of storing and releasing urine. Transitional epithelium is characterized by multiple layers of cells that can change shape from squamous when the bladder is empty to cuboidal or columnar when it is full. This ability to stretch and change shape allows the bladder to expand and contract as needed.Rate this question:

Correct Answer
A. All displayed answers are correctExplanation
Stratified squamous epithelium tissue is located in multiple areas of the human body, including the anal canal, mouth, vagina, and esophagus. This type of tissue is characterized by multiple layers of flat cells and is found in areas that require protection against friction and mechanical stress. Therefore, all of the displayed answers are correct as they represent different locations where stratified squamous epithelium tissue is present.Rate this question:

What is the structure with label "A"?
-
Globet cells
-
Cilia
-
Basement Membrane
-
Basal lamina
Correct Answer
A. Basement MembraneExplanation
The correct answer is Basement Membrane. The basement membrane is a thin, sheet-like structure that separates the epithelium from the underlying connective tissue. It provides support and anchorage for the epithelial cells and helps regulate the exchange of substances between the epithelium and the underlying tissue.Rate this question:

Stratified Columnar
Correct Answer
A. Stratified SquamousExplanation
The image to the right shows stratified squamous epithelial tissue. This type of tissue consists of multiple layers of flat cells that provide protection against mechanical stress and abrasion. It is commonly found in areas such as the skin, mouth, and esophagus. The stratified arrangement of cells allows for durability and resistance to wear and tear.Rate this question:
-
- 20.
This image is a stratified pseudosquamous epithelial tissue.
-
True
-
False
Correct Answer
A. FalseExplanation
The given statement is false because the image does not show a stratified pseudosquamous epithelial tissue. Pseudosquamous epithelial tissue is a type of epithelial tissue that appears to be stratified but is actually a single layer of cells. The image does not show any stratification or multiple layers of cells, so it cannot be a stratified pseudosquamous epithelial tissue.Rate this question:
-
- 21.
What is the name of this epithelial tissue?
-
Simple Cuboidal
-
Simple Columnar
-
Simple Squamous
-
Simple Transitional
Correct Answer
A. Simple SquamousExplanation
Simple squamous epithelial tissue is a type of epithelial tissue that consists of a single layer of flattened cells. These cells are thin and allow for the efficient diffusion of substances across their surface. They are found in areas where diffusion and filtration are important, such as the lining of blood vessels, air sacs in the lungs, and the kidney tubules. The cells of simple squamous epithelium are tightly packed together, providing a smooth and thin barrier for the exchange of gases, nutrients, and waste products.Rate this question:

What is the classification of this epithelial tissue?
-
Simple Squamous
-
Transitional Stretched
-
Transitional Relaxed
-
Pseudostratified
Correct Answer
A. Transitional StretchedExplanation
The correct answer is Transitional Stretched. This classification refers to a type of epithelial tissue that can stretch and expand in response to changes in volume. Transitional epithelium is found in organs like the urinary bladder, where it allows the tissue to accommodate the stretching that occurs when the bladder fills with urine. The term "stretched" indicates that the tissue is in a stretched or expanded state.Rate this question:

Stratified Squamous (nonkeratinized)
-
Stratified Cuboidal
-
Stratified Columnar
-
Stratified Transitional
Correct Answer
A. Stratified ColumnarExplanation
The correct answer is Stratified Columnar. This is because the image shows multiple layers of columnar cells stacked on top of each other. The cells have elongated nuclei and are taller than they are wide, which is characteristic of columnar epithelial tissue.Rate this question:

What of type of epithelial tissue is shown in the photo-micrograph?
-
Transitional
-
Simple Layer
-
Stratified Keratinized Squamous
-
Simple Columnar Ciliated
Correct Answer
A. TransitionalExplanation
The correct answer is transitional because the photo-micrograph shows a tissue that has multiple layers of cells with a unique appearance. Transitional epithelial tissue is found in organs that undergo stretching, such as the urinary bladder, and its cells can change shape depending on whether the organ is stretched or relaxed. This tissue is characterized by its ability to transition between a squamous shape when stretched and a cuboidal shape when relaxed.Rate this question:
-
- 26.
This is a stratified transitional ciliated epithelial tissue.
-
True
-
False
Correct Answer
A. FalseExplanation
The tissue shown in the image is transitional epithelium. Transitional epithelium is a type of stratified epithelial tissue that can stretch and is commonly found lining organs of the urinary system, such as the bladder. It is not ciliated, which is a characteristic of some other epithelial tissues like pseudostratified ciliated columnar epithelium found in the respiratory tract.Rate this question:

-
Transitional Stretched
Correct Answer
A. Stratified Squamous (nonkeratinized)Explanation
The correct answer is Stratified Squamous (keratinized). Multiple layers of flattened cells characterize this epithelial tissue. It is called "keratinized" because it does contain keratin, a tough protein that provides protection to the skin. This type of tissue is found in areas of the body that require protection against abrasion and friction, such as the lining of the mouth, esophagus, and vagina.Rate this question:
