Q: Which of the following equations best represents the relationship between the number of cell layers ($n$) and the type of epithelium, where $n = 1$ is simple and $n > 1$ is stratified?

$n = 1$ \Rightarrow \text{simple epithelium}$

Question 1

Which of the following best describes the primary function of epithelial tissue?

Accepted Answer

It covers body surfaces, lines cavities, and forms glands.

Question 2

A pathologist is most likely to use which scientific discipline to diagnose diseases by examining tissues?

Accepted Answer

Histology

Question 3

Which type of cell junction is primarily responsible for forming fluid-tight seals between adjacent cells?

Accepted Answer

Tight junctions

Question 4

Which tissue type is most likely to be avascular and rely on diffusion from underlying connective tissue for nutrients?

Accepted Answer

Epithelial tissue

Question 5

A patient suffers a tendon injury that takes over a year to heal, while a bone fracture heals in 8 weeks. What is the most likely explanation for this difference?

Accepted Answer

Bones are more vascularized than tendons, allowing faster healing.

Question 6

Which of the following is a correct pairing of connective tissue cell type and its activity level?

Accepted Answer

Blast cells: immature, more active

Question 7

Which connective tissue fiber type provides the greatest tensile strength and is often found in parallel bundles?

Accepted Answer

Collagen fibers

Question 8

A tissue sample from the small intestine shows a single layer of tall cells with microvilli. Which type of epithelium is this?

Accepted Answer

Simple columnar epithelium

Question 9

Which of the following equations correctly represents the relationship between tissue repair types, where $R$ is regeneration and $F$ is fibrosis, and $T$ is total repair?

Accepted Answer

$T = R + F$

Question 10

Which connective tissue type is most likely to be found in the walls of arteries, providing elasticity and strength?

Accepted Answer

Elastic connective tissue

Question 11

A biopsy reveals cells spaced between fine, interlacing fibers forming the framework of a lymph node. Which connective tissue is this?

Accepted Answer

Reticular connective tissue

Question 12

Which of the following best explains why epithelial tissue has a high capacity for regeneration?

Accepted Answer

Its cells divide rapidly to replace lost or damaged cells.

Question 13

Which type of epithelial tissue is specialized for stretching and is found lining the urinary bladder?

Accepted Answer

Transitional epithelium

Question 14

Which of the following is TRUE regarding the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones into interstitial fluid and then into the blood.

Question 15

Which of the following equations best represents the relationship between the number of cell layers ($n$) and the type of epithelium, where $n = 1$ is simple and $n > 1$ is stratified?

Accepted Answer

$n = 1$ \Rightarrow 	ext{simple epithelium}$

Question 16

Which connective tissue type is characterized by regularly arranged parallel bundles of collagen fibers and provides strong attachment between structures?

Accepted Answer

Dense regular connective tissue

Question 17

A patient with extensive tissue damage in the liver develops scar tissue that impairs function. Which process is responsible for this outcome?

Accepted Answer

Fibrosis

Question 18

Which of the following is NOT a function of connective tissue?

Accepted Answer

Absorption of nutrients

Question 19

Which type of cartilage is found in intervertebral discs and is characterized by thick bundles of collagen fibers?

Accepted Answer

Fibrocartilage

Question 20

Which of the following best describes the extracellular matrix of connective tissue?

Accepted Answer

It is composed of ground substance and fibers.
