Question 1

Which of the following is NOT a primary function of epithelial tissue?

Accepted Answer

Producing movement

Question 2

A tissue sample from the lining of the trachea shows cells with cilia on their apical surface. What is the main function of these cilia?

Accepted Answer

Moving mucus and trapped particles out of the airway

Question 3

Which of the following statements about epithelial tissue is TRUE?

Accepted Answer

Epithelial tissue is supported by underlying connective tissue

Question 4

A histology slide shows a single layer of tall, rectangular cells with nuclei located near the base. Which type of epithelium is this?

Accepted Answer

Simple columnar epithelium

Question 5

Which equation correctly represents the relationship between surface area ($A$) and absorption rate ($R$) in epithelial tissue, assuming absorption rate is directly proportional to surface area?

Accepted Answer

$R = kA$

Question 6

Which of the following cell junctions is most important for preventing leakage between adjacent epithelial cells in the intestinal lining?

Accepted Answer

Tight junctions

Question 7

A patient has damage to the basement membrane of their skin. Which of the following consequences is most likely?

Accepted Answer

Reduced support and separation between epithelium and connective tissue

Question 8

Which type of epithelial tissue would you expect to find lining the alveoli of the lungs, where rapid gas exchange occurs?

Accepted Answer

Simple squamous epithelium

Question 9

If a tissue sample contains multiple layers of flat cells, which type of epithelium is present?

Accepted Answer

Stratified squamous epithelium

Question 10

Which of the following best describes the difference between the apical and basal surfaces of epithelial cells?

Accepted Answer

The apical surface is exposed to the exterior or cavity, while the basal surface is attached to the basement membrane.

Question 11

Which of the following is a key characteristic of epithelial tissue that distinguishes it from connective tissue?

Accepted Answer

Epithelial tissue is avascular but innervated.

Question 12

A biopsy from the esophagus reveals several layers of cells, with the topmost cells being flat and scale-like. What is the most likely type of epithelium present?

Accepted Answer

Stratified squamous epithelium

Question 13

Which of the following is the correct sequence of steps for identifying epithelial tissue under a microscope?

Accepted Answer

Count the number of cell layers, determine the shape of the cells at the apical surface, then look for specializations like cilia or microvilli.

Question 14

Which of the following equations best represents the relationship between the rate of diffusion ($D$) across a simple squamous epithelium and the thickness ($T$) of the tissue, assuming all other factors are constant?

Accepted Answer

$D = \frac{k}{T}$

Question 15

Which of the following is a function of microvilli found on the apical surface of some epithelial cells?

Accepted Answer

Increasing surface area for absorption

Question 16

A tissue sample from the kidney tubules shows cells that are as tall as they are wide, with centrally located nuclei. Which type of epithelium is this?

Accepted Answer

Simple cuboidal epithelium

Question 17

Which of the following best explains why epithelial tissue is able to regenerate quickly after injury?

Accepted Answer

It has a high rate of cell division due to stem cells located near the basement membrane.

Question 18

Which of the following is the correct definition of histology?

Accepted Answer

The study of tissues

Question 19

Which of the following tissues is responsible for internal communication and integration in the body?

Accepted Answer

Nervous tissue

Question 20

A patient presents with a disorder affecting the tight junctions in their intestinal epithelium. Which symptom would most likely result?

Accepted Answer

Leakage of intestinal contents between cells
