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

Cardiac muscle cells have limited mitotic activity and rely on scar tissue formation

Question 8

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

Accepted Answer

Provide structural support and protection for neurons

Question 9

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 10

Which of the following equations correctly represents the relationship between tissue organization and organ systems?

Accepted Answer

$$Cells \rightarrow Tissues \rightarrow Organs \rightarrow Organ\ Systems$$

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

A patient suffers a deep cut that damages both the epidermis and underlying connective tissue. Which process is most likely to occur during healing?

Accepted Answer

Formation of scar tissue (fibrosis)

Question 14

Which of the following is a characteristic of simple columnar epithelium?

Accepted Answer

Cells are taller than they are wide and often involved in absorption

Question 15

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

Accepted Answer

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

Question 16

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

Accepted Answer

Fibroblasts

Question 17

Which of the following best describes the function of muscle tissue?

Accepted Answer

Contracts to produce movement

Question 18

Which of the following is a correct statement about the regeneration capacity of tissues after injury?

Accepted Answer

Epithelial tissue and most connective tissues regenerate well; cardiac muscle and cartilage regenerate poorly

Question 19

Which of the following is a real-world consequence of defective anchoring fibers in the basement membrane of epithelial tissue?

Accepted Answer

Formation of blisters and increased risk of infection

Question 20

Which equation best represents the process of inflammation following tissue injury?

Accepted Answer

$$Tissue\ Injury \rightarrow Increased\ Blood\ Flow \rightarrow Swelling \rightarrow Repair$$
