Question 7

If you observe an epithelial tissue with cells of varying heights and nuclei at different levels, but all cells touch the basement membrane, what type of tissue are you likely viewing?

Accepted Answer

Pseudostratified columnar epithelium

Question 8

Which equation best represents the surface area ($A$) of a simple squamous epithelial cell, assuming it is roughly circular with diameter $d$?

Accepted Answer

$A = \frac{\pi d^2}{4}$

Question 9

Which of the following is a key function of stratified squamous epithelium in the skin?

Accepted Answer

Protection against abrasion

Question 10

Accepted Answer

Stratified cuboidal epithelium

Question 11

Which of the following statements about the apical surface of epithelial tissue is correct?

Accepted Answer

It faces the lumen or external environment

Question 12

Which type of epithelial tissue is specialized for absorption and often contains microvilli on its apical surface?

Accepted Answer

Simple columnar epithelium

Question 13

A pathologist is examining a tissue sample and notes that the nuclei are oval and located near the basal surface. The cells are taller than they are wide. What type of epithelial tissue is this?

Accepted Answer

Simple columnar epithelium

Question 14

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

Accepted Answer

Cells are highly vascularized

Question 15

Accepted Answer

$n_{avg} = \frac{N}{C}$

Question 16

Which type of epithelial tissue is most likely to be found in areas subject to wear and tear, such as the lining of the mouth?

Accepted Answer

Stratified squamous epithelium

Question 17

Which of the following best describes the arrangement of nuclei in pseudostratified columnar epithelium?

Accepted Answer

Nuclei are at varying levels

Question 18

A tissue sample from the small intestine shows cells with microvilli and nuclei located basally. What is the primary function of this tissue?

Accepted Answer

Absorption of nutrients

Question 19

Which of the following equations correctly calculates the total surface area ($A_{total}$) of $n$ simple cuboidal epithelial cells, each with surface area $A_{cell}$?

Accepted Answer

$A_{total} = n 	imes A_{cell}$
