1.
What type of tissue is this?
Correct Answer
D. Stratified Squamous Epithelial
Explanation
This tissue is classified as stratified squamous epithelial because it consists of multiple layers of flattened cells. The presence of multiple layers allows for protection against mechanical stress and abrasion, which is a characteristic feature of stratified squamous epithelial tissue.
2.
What type of tissue is this?
Correct Answer
A. Simple Columnar Epithelial
Explanation
The tissue in question is identified as simple columnar epithelial. This type of tissue is characterized by its tall, elongated cells that are arranged in a single layer. The cells have a column-like shape and their nuclei are located towards the base of the cells. Simple columnar epithelial tissue is typically found lining the digestive tract, where it functions in absorption and secretion.
3.
What type of tissue is this?
Correct Answer
C. Simple Squamous Epithelial
Explanation
The given tissue is identified as simple squamous epithelial tissue. This type of tissue is characterized by a single layer of flat cells that are tightly packed together. It is found in areas where diffusion and filtration occur, such as the lining of blood vessels, air sacs of the lungs, and the lining of the heart and abdominal cavity. Its thin and flat structure allows for efficient exchange of substances and gases.
4.
What type of tissue is this?
Correct Answer
A. Simple Cuboidal
Explanation
Simple cuboidal tissue is a type of epithelial tissue that consists of a single layer of cube-shaped cells. These cells have a centrally located nucleus and are specialized for secretion and absorption. They are commonly found in the lining of small ducts and tubules in various organs, such as the kidneys and glands. This tissue provides protection, secretion, and absorption functions in the body.
5.
What type of tissue is this?
Correct Answer
B. Simple Columnar
Explanation
Simple columnar tissue is a type of epithelial tissue that is composed of a single layer of tall, elongated cells. These cells are closely packed together and have their nuclei located near the base of the cells. This type of tissue is commonly found in the lining of the digestive tract, where it helps with absorption and secretion. It provides protection and also allows for the movement of substances across its surface.
6.
What type of tissue is this?
Correct Answer
D. Stratified Cuboidal
Explanation
The tissue in question is stratified cuboidal. This type of tissue consists of multiple layers of cuboidal cells. The stratified arrangement provides protection and support to the underlying tissues. Cuboidal cells are cube-shaped and have a single layer in simple cuboidal tissue, but in stratified cuboidal tissue, they are stacked in multiple layers. This type of tissue is found in certain ducts and glands, where it helps with secretion and absorption.
7.
What type of tissue is this?
Correct Answer
G. Transitional
Explanation
Transitional tissue is a type of epithelial tissue found in organs that need to stretch and expand, such as the urinary bladder. It is characterized by multiple layers of cells that can change shape and stretch without tearing. This tissue allows the bladder to expand as it fills with urine and contract as it empties.
8.
What type of tissue is this?
Correct Answer
G. Transitional
Explanation
The tissue shown in the question is transitional epithelium. This type of tissue is found in organs that need to stretch and accommodate changes in volume, such as the urinary bladder. Transitional epithelium is characterized by multiple layers of cells that can change shape from cuboidal to squamous when the organ is stretched.
9.
What type of tissue is this?
Correct Answer
H. Pseudostratified
Explanation
Pseudostratified tissue is a type of epithelial tissue that appears to be stratified but is actually a single layer of cells. It is characterized by cells of varying heights, giving the appearance of multiple layers. Pseudostratified tissue is typically found in the respiratory tract, where it helps to trap and move mucus and particles. It also contains cilia, which aid in the movement of mucus.
10.
What type of tissue is this?
Correct Answer
H. Pseudostratified
Explanation
A pseudostratified tissue appears to have multiple layers of cells, but in reality, all the cells are attached to the basement membrane. This type of tissue is typically found in the respiratory tract, where it helps to move mucus and trap particles. It is called pseudostratified because the nuclei of the cells are at different levels, giving the appearance of stratification. However, all the cells are in contact with the basement membrane, making it a single layer of cells.
11.
What type of tissue is this?
Correct Answer
H. Pseudostratified columnar epithelium
Explanation
The given tissue type is the pseudostratified columnar epithelium. Pseudostratified epithelium appears to have multiple layers of cells, but all the cells are actually attached to the basement membrane. This type of tissue is typically found in the respiratory tract, where it helps to move mucus and trap particles, protecting the underlying tissues. It has cilia on the surface of the cells, which aid in moving mucus and debris out of the respiratory tract.
12.
What type of tissue is this?
Correct Answer
A. Simple Cuboidal
Explanation
Simple cuboidal tissue is a type of epithelial tissue that consists of a single layer of cube-shaped cells. These cells have a centrally located nucleus and are involved in secretion and absorption. This type of tissue is found in various organs and structures such as the kidneys, glands, and certain parts of the respiratory and reproductive systems.
13.
What type of tissue is this?
Correct Answer
B. Simple Columnar
Explanation
The given correct answer is Simple Columnar. This type of tissue is characterized by a single layer of tall, rectangular cells. It is commonly found lining the digestive tract, where it functions in absorption and secretion. The cells of simple columnar tissue are tightly packed together and have specialized structures such as microvilli or goblet cells, depending on their location within the body. This tissue type provides protection and helps in the movement of substances across its surface.
14.
What type of tissue is this?
Correct Answer
D. Stratified Cuboidal
Explanation
The tissue in question is stratified cuboidal. This type of tissue is composed of multiple layers of cube-shaped cells. It is typically found in areas where protection and secretion are necessary, such as the sweat glands and the ducts of certain glands. The stratified arrangement of cells provides strength and support to the tissue.
15.
What type of tissue is this?
Correct Answer
F. Stratified Squamous
Explanation
The tissue shown in the question is stratified squamous. This can be determined by the multiple layers of flat cells that make up the tissue. Stratified squamous epithelial tissue is found in areas that experience wear and tear, such as the skin and the lining of the mouth and esophagus. It provides protection against abrasion and helps to prevent the entry of pathogens.
