Question 1

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

Accepted Answer

It is avascular but innervated, relying on diffusion for nutrients.

Question 2

A patient suffers from a condition where rapid diffusion of gases in the lungs is impaired. Which epithelial tissue is most likely affected?

Accepted Answer

Simple squamous epithelium

Question 3

Which of the following best describes the function of goblet cells found in some epithelial tissues?

Accepted Answer

They produce mucin, which forms mucus for lubrication.

Question 4

A biopsy of a patient's skin reveals multiple layers of cells with the surface layer being flat and scale-like. Which type of epithelium is this?

Accepted Answer

Stratified squamous epithelium

Question 5

Which of the following statements about connective tissue is TRUE?

Accepted Answer

Connective tissue cells are suspended in an extracellular matrix.

Question 6

A ligament is torn during a sports injury. Which type of connective tissue is primarily affected?

Accepted Answer

Dense regular connective tissue

Question 7

Which of the following best explains why cartilage heals slowly after injury?

Accepted Answer

Cartilage lacks nerve fibers and is avascular, limiting nutrient supply.

Question 8

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

Accepted Answer

Providing high tensile strength to tissues

Question 9

Which of the following is a function of adipose tissue?

Accepted Answer

Shock absorption and energy storage

Question 10

A histological slide shows a single layer of tall, closely packed cells, some with cilia, and goblet cells. This tissue is most likely found in which organ?

Accepted Answer

Small intestine

Question 11

Which of the following best describes the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones into interstitial fluid; exocrine glands secrete products onto epithelial surfaces.

Question 12

Which type of connective tissue fiber allows tissues to stretch and recoil, such as in the walls of arteries?

Accepted Answer

Elastic fibers

Question 13

A patient with liver damage has impaired synthesis of proteoglycans. Which component of connective tissue is most directly affected?

Accepted Answer

Ground substance

Question 14

Which of the following best explains why areolar connective tissue is considered a 'packing material' in the body?

Accepted Answer

It supports and binds other tissues, holding body fluids and defending against infection.

Question 15

A patient presents with swelling in the lymph nodes. Which connective tissue type forms the supportive framework of lymph nodes?

Accepted Answer

Reticular connective tissue

Question 16

Which of the following is a correct sequence of events for the regeneration of stratified epithelial tissue after injury?

Accepted Answer

Cells divide in the basal layer and migrate toward the surface.

Question 17

Which of the following best describes the structure and function of pseudostratified columnar epithelium?

Accepted Answer

It is a single layer of cells of varying heights, involved in secretion and movement of mucus.

Question 18

Which of the following equations best represents the relationship between the volume of ground substance ($V_{gs}$), the amount of water trapped ($W$), and the concentration of proteoglycans ($C_p$) in connective tissue?

Accepted Answer

$V_{gs} = W + (k 	imes C_p)$,\ where\ k\ is\ a\ proportionality\ constant$

Question 19

A patient with a genetic disorder affecting the formation of the basement membrane would most likely have issues with which tissue type?

Accepted Answer

Epithelial tissue

Question 20

Which of the following best explains why dense irregular connective tissue is found in the dermis of the skin?

Accepted Answer

Its fibers are arranged in multiple directions, providing strength to resist tension from various angles.
