Question 1

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

Accepted Answer

Contains abundant blood vessels

Question 2

A patient presents with a tumor that has invaded underlying tissues beyond the basement membrane. What property of epithelial tissue has been compromised, and what is the clinical significance?

Accepted Answer

Basement membrane boundary; allows cancerous cells to spread

Question 3

Which type of epithelial tissue is best suited for rapid diffusion and is found in locations such as the alveoli of the lungs and the lining of blood vessels?

Accepted Answer

Simple squamous epithelium

Question 4

A gland that releases its product by exocytosis without damaging the cell is classified as which type of exocrine gland?

Accepted Answer

Merocrine

Question 5

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

Accepted Answer

Increase surface area for absorption

Question 6

A histology slide shows a tissue with multiple layers of flat cells at the surface, found lining the esophagus. What is the most likely type of epithelium?

Accepted Answer

Stratified squamous epithelium

Question 7

Which equation best represents the relationship between tissue regeneration rate ($$R$$), nutrient availability ($$N$$), and cell division rate ($$D) in $$epithelial tissue?

Accepted Answer

$$R = N 	imes D$$

Question 8

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

Accepted Answer

Epithelial tissue is avascular and receives nutrients by diffusion from underlying connective tissue.

Question 9

Which type of gland releases hormones directly into the bloodstream and does not have ducts?

Accepted Answer

Endocrine gland

Question 10

A tissue sample from the urinary bladder shows cells that change shape when stretched. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 11

Which of the following is a function of epithelial tissue that is critical for maintaining homeostasis?

Accepted Answer

Protection, absorption, filtration, excretion, and sensory reception

Question 12

Which of the following best describes the difference between simple and stratified epithelia?

Accepted Answer

Simple epithelia have one layer of cells; stratified epithelia have multiple layers

Question 13

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

Accepted Answer

Stratified squamous epithelium — skin surface (epidermis)

Question 14

Which of the following statements about glandular epithelia is correct?

Accepted Answer

Exocrine glands secrete their products onto body surfaces or into body cavities via ducts.

Question 15

A multicellular exocrine gland with a branched duct and sac-like secretory units is classified as:

Accepted Answer

Compound alveolar gland

Question 16

Which of the following best explains why epithelial cells have a high regenerative capacity?

Accepted Answer

They are exposed to friction and hostile substances, requiring frequent replacement.

Question 17

Which of the following is a correct sequence for preparing tissue for microscopic examination?

Accepted Answer

Fixed, sectioned, stained

Question 18

A tissue sample from the trachea shows cells that appear to be multi-layered but all touch the basement membrane. What type of epithelium is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 19

Which of the following equations best represents the total surface area ($$A) $$available for absorption in an epithelial tissue with $$n$$ microvilli, each with surface area $$a$$?

Accepted Answer

$$A = n 	imes a$$
