Question 1

Which of the following is NOT one of the four primary tissue types found in the human body?

Accepted Answer

Adipose

Question 2

The extracellular matrix (ECM) is primarily associated with which tissue type, and what is its main function?

Accepted Answer

Connective tissue; providing structural support and separating tissues

Question 3

A histologist is examining a tissue sample under a microscope. The tissue appears transparent before staining. What is the most likely reason for this?

Accepted Answer

The tissue has not yet been stained, so cellular structures are not visible

Question 4

Which of the following statements about epithelial tissue is TRUE?

Accepted Answer

Epithelial tissue forms sheets of tightly packed cells on surfaces and lines cavities

Question 5

How many major functional groups can epithelial tissue be categorized into, and what are they?

Accepted Answer

Two: covering/lining and glandular

Question 6

Which of the following is a primary function of glandular epithelium?

Accepted Answer

Production and secretion of substances via glands

Question 7

A nutrient in the small intestine is absorbed into the bloodstream. If it must pass through two layers of epithelial cells, how many times does it cross a plasma membrane?

Accepted Answer

$$4$$

Question 8

Which of the following is NOT a commonly recognized characteristic of epithelial tissue?

Accepted Answer

Contains abundant blood vessels

Question 9

The basement membrane of epithelial tissue consists of two layers. Which layer is produced by connective tissue?

Accepted Answer

Reticular lamina

Question 10

Which statement best explains why epithelial tissue is highly regenerative?

Accepted Answer

It is constantly exposed to physical and chemical stress, requiring frequent cell replacement

Question 11

Which of the following is a correct pairing of epithelial tissue structure and function?

Accepted Answer

Simple cuboidal epithelium; secretion in glands

Question 12

Which tissue type is responsible for detecting stimuli and transmitting electrical signals throughout the body?

Accepted Answer

Nervous tissue

Question 13

A histologist is asked to identify the tissue type lining the airways. Which of the following is the most likely answer?

Accepted Answer

Pseudostratified columnar epithelium

Question 14

Which of the following best describes the function of the apical surface of epithelial tissue?

Accepted Answer

Faces the lumen or external environment, allowing interaction with substances

Question 15

Which of the following is NOT a function of covering and lining epithelium?

Accepted Answer

Production of hormones

Question 16

Which of the following statements is TRUE regarding the relationship between epithelial and connective tissue?

Accepted Answer

Connective tissue provides nutrients and support to epithelial tissue via the basement membrane

Question 17

Which of the following is a plausible consequence of the avascular nature of epithelial tissue?

Accepted Answer

Epithelial tissue relies on diffusion from underlying connective tissue for nutrients

Question 18

Which of the following is NOT a role of the basement membrane in epithelial tissue?

Accepted Answer

Supplying blood directly to epithelial cells

Question 19

Which of the following would a histologist NOT be expected to do?

Accepted Answer

Prepare a sample of lung tissue using the Gram stain technique to identify bacteria

Question 20

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

Accepted Answer

Prevent leakage of substances between adjacent cells
