Question 1

Which of the following best describes the main structural difference between epithelial tissue and connective tissue proper?

Accepted Answer

Epithelial tissue consists of tightly packed cells with little extracellular matrix, while connective tissue has fewer cells and abundant extracellular matrix.

Question 2

A patient suffers a tear in a tendon. Which type of connective tissue proper is most likely affected?

Accepted Answer

Dense regular connective tissue

Question 3

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

Accepted Answer

It contains a large amount of extracellular matrix.

Question 4

Which of the following is the primary function of simple squamous epithelium?

Accepted Answer

Facilitation of diffusion and filtration

Question 5

A biopsy of a patient's skin reveals multiple layers of flat cells at the surface. Which type of epithelium is this?

Accepted Answer

Stratified squamous epithelium

Question 6

Which of the following statements about the extracellular matrix (ECM) is TRUE?

Accepted Answer

The ECM is composed of ground substance and fibers.

Question 7

A 45-year-old female is diagnosed with an aortic aneurysm. Which connective tissue component is most likely compromised?

Accepted Answer

Elastic fibers

Question 8

Which of the following is NOT a useful way to classify an epithelium?

Accepted Answer

Finding the location of the nuclei in the cell

Question 9

Which type of connective tissue proper provides a flexible framework for organs such as the spleen and lymph nodes?

Accepted Answer

Reticular connective tissue

Question 10

Which cell type is primarily responsible for producing collagen fibers in connective tissue proper?

Accepted Answer

Fibroblasts

Question 11

A tissue sample shows a single layer of tall, rectangular cells with nuclei aligned near the base. Which type of epithelium is this?

Accepted Answer

Simple columnar epithelium

Question 12

Which of the following best explains why epithelial tissue heals quickly after injury?

Accepted Answer

It has a high rate of cell division.

Question 13

Which of the following is a function of areolar connective tissue?

Accepted Answer

Binding and packing materials around organs

Question 14

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

Accepted Answer

Epithelial cells have an apical surface facing the lumen and a basal surface attached to the basement membrane.

Question 15

A tissue sample contains many parallel bundles of collagen fibers and few cells. Which tissue is this most likely to be?

Accepted Answer

Dense regular connective tissue

Question 16

Which of the following equations best represents the relationship between tissue, organ, and organ system?

Accepted Answer

$$Tissue + Tissue + Tissue + ... = Organ$$

Question 17

Which of the following is a distinguishing feature of pseudostratified columnar epithelium?

Accepted Answer

It appears to have multiple layers due to nuclei at different levels, but all cells touch the basement membrane.

Question 18

Which of the following best explains why nutrients must diffuse from underlying connective tissue into epithelial tissue?

Accepted Answer

Epithelial tissue lacks blood vessels.

Question 19

A patient with a genetic defect in collagen synthesis would most likely have problems with which tissue type?

Accepted Answer

Connective tissue proper

Question 20

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

Accepted Answer

They prevent leakage of substances between adjacent cells.
