Question 1

Which of the following best describes the function of the extracellular matrix (ECM) in connective tissue?

Accepted Answer

It is a combination of complex molecules found outside connective tissue cells, providing structural and biochemical support.

Question 2

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

Accepted Answer

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

Question 3

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

Accepted Answer

Contraction

Question 4

How many major functional groups can epithelial tissue be categorized into, based on the provided study materials?

Accepted Answer

2

Question 5

Which of the following statements is true about all epithelial tissue?

Accepted Answer

All epithelial tissue has one surface that is adjacent to an open space.

Question 6

A nutrient in the small intestine is absorbed into the bloodstream. It must pass through the epithelial tissue lining the intestine. If the nutrient moves from the lumen to the blood, how many times does it cross an epithelial cell membrane?

Accepted Answer

$$2$$

Question 7

Which of the following is a commonly recognized characteristic of epithelial tissue?

Accepted Answer

Highly regenerative

Question 8

Which layer of the basement membrane is produced by connective tissue?

Accepted Answer

Reticular lamina

Question 9

Why are epithelial tissues described as avascular but innervated?

Accepted Answer

They lack blood vessels but contain nerve endings.

Question 10

Which of the following best explains why most cancers develop from epithelial tissue?

Accepted Answer

Epithelial tissue is highly regenerative, increasing the chance of mutations during cell division.

Question 11

A tissue sample is composed of tightly packed cells with little extracellular matrix, forming a barrier on the surface of an organ. Which tissue type is this most likely to be?

Accepted Answer

Epithelial tissue

Question 12

Which of the following is a function of glandular epithelium?

Accepted Answer

Production of enzymes and hormones

Question 13

Which of the following best describes the polarity of epithelial tissue?

Accepted Answer

The tissue has a distinct apical surface facing an open space and a basal surface attached to the basement membrane.

Question 14

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

Accepted Answer

Producing hormones

Question 15

A histologist is asked to identify the primary function of the epithelium lining the bladder. Which function should be selected?

Accepted Answer

Protection

Question 16

Which of the following best explains why epithelial tissue is supported by connective tissue?

Accepted Answer

Connective tissue provides nutrients and removes wastes for the avascular epithelium.

Question 17

Which of the following is a correct sequence for the passage of a substance from the lumen of the intestine to the blood through epithelial tissue?

Accepted Answer

Lumen $$\rightarrow$$ apical membrane $$\rightarrow$$ cytoplasm $$\rightarrow$$ basal membrane $$\rightarrow$$ blood

Question 18

Which of the following is a true statement about the basement membrane of epithelial tissue?

Accepted Answer

It consists of two layers: the basal lamina (from epithelial cells) and the reticular lamina (from connective tissue).

Question 19

Which of the following best describes the relationship between epithelial and connective tissue?

Accepted Answer

Epithelial tissue is supported by connective tissue, which provides nutrients and structural support.

Question 20

Which of the following is a reason why epithelial tissue is described as highly regenerative?

Accepted Answer

It is frequently exposed to mechanical and chemical stress, requiring constant cell replacement.
