Question 1

Which of the following best describes the primary function of epithelial tissue in the human body?

Accepted Answer

Covers exposed surfaces and lines internal passageways

Question 2

A patient presents with blisters and sores due to a genetic mutation affecting the COL7A1 gene. Which tissue type is primarily compromised in this condition?

Accepted Answer

Connective tissue

Question 3

Which type of epithelial cell is best suited for rapid diffusion and is commonly found lining the alveoli of the lungs?

Accepted Answer

Simple squamous

Question 4

Which of the following cell junctions is responsible for preventing the passage of water and solutes between adjacent epithelial cells?

Accepted Answer

Tight junctions

Question 5

A gland that releases its product by exocytosis without damaging the cell is classified as which type of gland?

Accepted Answer

Merocrine gland

Question 6

Which connective tissue fiber type provides the greatest tensile strength and is most abundant in tendons?

Accepted Answer

Collagen fibers

Question 7

Which of the following best explains why cardiac muscle tissue has limited ability to regenerate after injury?

Accepted Answer

Its cells are terminally differentiated and do not divide

Question 8

Which equation best represents the relationship between tissue repair and scar formation (fibrosis) after injury?

Accepted Answer

$$T_{repair} = N_{tissue} + S_{fibrosis}$$

Question 9

Which of the following is a function of neuroglia in neural tissue?

Accepted Answer

Provide structural support and protection for neurons

Question 10

A tissue sample from the urinary bladder shows cells that change shape when stretched. What type of epithelium is present?

Accepted Answer

Transitional epithelium

Question 11

Which of the following best describes the role of the basement membrane in epithelial tissue?

Accepted Answer

It anchors epithelial cells to underlying connective tissue

Question 12

Which type of connective tissue is characterized by a mineralized matrix and is responsible for structural support and protection?

Accepted Answer

Bone

Question 13

Which of the following is a correct pairing of muscle tissue type and its primary function?

Accepted Answer

Cardiac muscle: rhythmic contraction of the heart

Question 14

Which equation best represents the rate of tissue regeneration ($$R) in $$epithelial tissue, given the number of stem cells ($$N) $$and their division rate ($$D$$)?

Accepted Answer

$$R = N 	imes D$$

Question 15

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

Accepted Answer

Conducting electrical impulses

Question 16

A patient suffers a deep cut that damages both epithelial and connective tissues. Which process is most likely to occur during healing?

Accepted Answer

Inflammation followed by fibrosis and scar tissue formation

Question 17

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

Accepted Answer

Exocrine glands secrete products onto epithelial surfaces; endocrine glands release hormones into the blood

Question 18

Which of the following cell types is responsible for producing collagen fibers in connective tissue?

Accepted Answer

Fibroblasts

Question 19

Which of the following best explains why stratified squamous epithelium is found in areas subject to abrasion, such as the skin and esophagus?

Accepted Answer

It provides greater protection due to multiple cell layers

Question 20

Which equation best represents the total tissue volume ($$V_{total}) in $$connective tissue, given the volume of matrix ($$V_{matrix}) $$and the volume of cells ($$V_{cells}$$)?

Accepted Answer

$$V_{total} = V_{matrix} + V_{cells}$$
