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 small intestine shows cells with microvilli on their apical surface. What is the main function of these microvilli?

Accepted Answer

Increasing surface area for absorption

Question 3

Which type of epithelial tissue is best suited for rapid diffusion and filtration, and where is it commonly found?

Accepted Answer

Simple squamous epithelium; found in alveoli of lungs

Question 4

Which of the following statements about epithelial tissue is TRUE?

Accepted Answer

Epithelial tissue is avascular but innervated

Question 5

A histology slide shows multiple layers of flat cells at the surface and cuboidal cells at the base. What type of epithelium is this?

Accepted Answer

Stratified squamous epithelium

Question 6

Which equation best represents the relationship between surface area ($$A) $$and absorption rate ($$R) in $$epithelial tissue with microvilli?

Accepted Answer

$$R \propto A$$

Question 7

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

Accepted Answer

Tight junctions

Question 8

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

Accepted Answer

Loss of structural support and increased risk of tissue detachment

Question 9

Which type of epithelial tissue lines the kidney tubules and is specialized for secretion and absorption?

Accepted Answer

Simple cuboidal epithelium

Question 10

If the rate of epithelial cell regeneration is $$r$$ cells/day and the tissue is damaged, which equation best describes the time ($$t) $$needed to replace $$N$$ lost cells?

Accepted Answer

$$t = \frac{N}{r}$$

Question 11

Which of the following is a key difference between simple and stratified epithelia?

Accepted Answer

Simple epithelia have one layer of cells; stratified epithelia have two or more layers

Question 12

Which tissue type is responsible for internal communication and integration in the body?

Accepted Answer

Nervous tissue

Question 13

A biopsy from the esophagus shows many layers of cells with flattened surface cells. What is the main protective function of this tissue?

Accepted Answer

Protection against abrasion

Question 14

Which of the following best describes the location of the apical surface in epithelial tissue?

Accepted Answer

It is the upper free surface exposed to the exterior or cavity

Question 15

Which of the following is TRUE regarding the blood supply to epithelial tissue?

Accepted Answer

Epithelial tissue is avascular and receives nutrients from underlying connective tissue

Question 16

Which of the following is a function of connective tissue?

Accepted Answer

Support and protection

Question 17

A tissue sample from 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 18

Which of the following best describes the basement membrane in epithelial tissue?

Accepted Answer

It defines the epithelial boundary and reinforces the tissue

Question 19

Which type of epithelial tissue is found on the skin surface and provides protection against mechanical stress?

Accepted Answer

Stratified squamous epithelium

Question 20

If the thickness of a stratified squamous epithelium increases from $$d_1 to$$ $$d_2$$, what is the likely effect on its protective function?

Accepted Answer

Protection increases as thickness increases ($$d_2$$ \u003e $$d_1)$$
