Question 1

Which of the following is NOT a special characteristic of epithelial tissue?

Accepted Answer

It is highly vascularized, containing many blood vessels.

Question 2

A patient with Celiac disease develops a 'leaky gut' due to damage to which specific structure between epithelial cells?

Accepted Answer

Tight junctions

Question 3

Which of the following best describes the function of microvilli on the apical surface of epithelial cells?

Accepted Answer

They increase the surface area to allow for the transport of more ions into the cell.

Question 4

Which type of epithelial tissue would you expect to find lining the air sacs (alveoli) of the lungs, and why?

Accepted Answer

Simple squamous epithelium, because it allows for rapid diffusion of gases.

Question 5

Which of the following best describes a stratified cuboidal epithelium?

Accepted Answer

Multiple layers of cube-shaped cells

Question 6

A gland that releases its secretions into the bloodstream rather than through ducts is classified as:

Accepted Answer

Endocrine

Question 7

Which of the following statements about the basement membrane is TRUE?

Accepted Answer

It consists of the basal lamina and reticular fibers of the underlying connective tissue.

Question 8

Which epithelial tissue type is best suited for areas of the body subject to abrasion, such as the skin or oral cavity?

Accepted Answer

Stratified squamous epithelium

Question 9

A tissue sample shows a single layer of tall, closely packed cells, some of which have cilia. Which of the following is the most likely function of this tissue?

Accepted Answer

Absorption and movement of mucus

Question 10

Which of the following best explains why epithelial tissues have a high rate of regeneration?

Accepted Answer

They are frequently exposed to friction and environmental damage, requiring constant cell replacement.

Question 11

Which of the following is a correct pairing of epithelial type and its primary function?

Accepted Answer

Simple cuboidal epithelium – absorption and secretion

Question 12

A tissue is described as having several layers of cells, with the apical layer being tall and column-shaped. What is the correct name for this tissue?

Accepted Answer

Stratified columnar epithelium

Question 13

Which of the following best describes the function of cilia on epithelial cells?

Accepted Answer

Movement of mucus or other substances across the cell surface

Question 14

Which of the following is a correct description of pseudostratified columnar epithelium?

Accepted Answer

A single layer of cells of varying heights, all touching the basement membrane

Question 15

Which of the following is a function of the basal lamina in epithelial tissue?

Accepted Answer

Providing a surface for new epithelial cells to grow

Question 16

Which of the following best describes the difference between membranous and glandular epithelium?

Accepted Answer

Membranous epithelium covers and lines surfaces, while glandular epithelium produces secretions.

Question 17

Which of the following is NOT a major tissue type in the human body?

Accepted Answer

Bone

Question 18

A gland with a branched duct and tube-shaped secretory portions is classified as:

Accepted Answer

Compound tubular

Question 19

Which of the following best explains why stratified epithelia are named according to the shape of their apical layer?

Accepted Answer

The apical layer is the most exposed and determines the tissue's function.

Question 20

A patient presents with a tumor in a gland that secretes hormones directly into the blood. Which type of gland is most likely affected?

Accepted Answer

Endocrine gland
