Question 1

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

Accepted Answer

Contraction

Question 2

Epithelial tissue is described as avascular but innervated. What does this mean?

Accepted Answer

It does not contain blood vessels but does have nerve fibers.

Question 3

Which structure attaches the basal surface of epithelial cells to underlying connective tissue?

Accepted Answer

Basal lamina

Question 4

A tissue sample from the lining of the small intestine shows tall, closely packed cells with microvilli. What type of epithelial tissue is this?

Accepted Answer

Simple columnar epithelium

Question 5

Which of the following best describes the function of tight junctions in epithelial tissue?

Accepted Answer

Prevent substances from passing between adjacent cells

Question 6

Stratified squamous epithelium is most likely to be found in which location?

Accepted Answer

Skin surface

Question 7

Which of the following statements about epithelial tissue regeneration is correct?

Accepted Answer

Epithelial cells have a high regenerative capacity if supplied with adequate nutrients.

Question 8

A glandular epithelium is primarily involved in which function?

Accepted Answer

Secretion of substances

Question 9

Which of the following is a distinguishing characteristic of epithelial tissue?

Accepted Answer

Exhibits polarity with distinct apical and basal surfaces

Question 10

If a tissue sample is described as 'stratified cuboidal epithelium,' what does this mean?

Accepted Answer

It is multiple layers of cube-shaped cells.

Question 11

Which formula best represents the relationship between diffusion rate ($R$) and distance ($d$) for nutrients reaching avascular epithelial cells?

Accepted Answer

$R = \frac{k}{d}$

Question 12

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

Accepted Answer

Reduced ability to resist stretching and tearing

Question 13

Which type of epithelial tissue is best suited for rapid diffusion and is found lining blood vessels?

Accepted Answer

Simple squamous epithelium

Question 14

Which of the following is true about the apical surface of epithelial cells?

Accepted Answer

It is exposed to the surface or cavity and may have microvilli.

Question 15

Which of the following best explains why epithelial tissues are able to regenerate quickly?

Accepted Answer

They receive nutrients by diffusion and have high rates of cell division.

Question 16

Which type of epithelial tissue is found lining the bladder and is capable of stretching?

Accepted Answer

Transitional epithelium

Question 17

Which of the following lateral contacts is responsible for preventing leakage of extracellular fluid between epithelial cells?

Accepted Answer

Tight junctions

Question 18

Which of the following is a correct pairing of epithelial tissue type and its location?

Accepted Answer

Simple squamous epithelium – lining of blood vessels

Question 19

Which of the following best describes the basement membrane?

Accepted Answer

A structure made up of basal and reticular lamina that reinforces the epithelial sheet

Question 20

Which of the following is a real-life consequence of damage to the tight junctions in intestinal epithelial cells?

Accepted Answer

Leakage of digestive enzymes into underlying tissues, causing inflammation
