Question 1

Refer to the two images provided. What is the main difference in the way the tissue is sectioned between the first and second image?

Accepted Answer

The first image is a longitudinal section, and the second image is a transverse section of the same tissue.

Question 2

Which type of epithelial tissue is most likely depicted in both images, based on the arrangement and shape of the cells lining the tubules?

Accepted Answer

Simple cuboidal epithelium

Question 3

If the tissue shown in the images is from the kidney, what is the primary function of the epithelial cells lining these tubules?

Accepted Answer

Absorption and secretion of substances during urine formation

Question 4

Which of the following best describes the arrangement of nuclei in the epithelial cells seen in the first image?

Accepted Answer

Nuclei are round and centrally located within the cells

Question 5

Which of the following statements is true regarding the tissue organization seen in the second image?

Accepted Answer

The tissue is composed of a single layer of cuboidal cells surrounding a lumen.

Question 6

If a toxin disrupted the function of these epithelial cells, which physiological process would be most directly affected?

Accepted Answer

Filtration and reabsorption in the kidney

Question 7

Which of the following best describes the polarity of the epithelial cells seen in the images?

Accepted Answer

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

Question 8

Which of the following best explains why the cells in the images appear cuboidal rather than squamous or columnar?

Accepted Answer

The cells are as tall as they are wide, giving them a cube-like appearance.

Question 9

Which of the following is a likely function of the basement membrane underlying the epithelial cells in these images?

Accepted Answer

It anchors the epithelium to the underlying connective tissue.

Question 10

If the tissue in the images was stained to highlight protein fibers in the matrix, which connective tissue component would be most visible surrounding the tubules?

Accepted Answer

Collagen fibers
