Question 1

Which of the following best describes the main function of the extracellular matrix (ECM) in tissues?

Accepted Answer

It provides strength, regulates cell behavior, and holds cells in place.

Question 2

A patient presents with a genetic disorder that affects the production of collagen fibers. Which tissue function is most likely to be compromised?

Accepted Answer

Resistance to tensile and compressive forces

Question 3

Which type of cell junction would be most important in preventing the leakage of digestive enzymes between the cells lining the stomach?

Accepted Answer

Tight (occluding) junctions

Question 4

Which of the following epithelial tissues is best adapted for rapid diffusion of gases in the lungs?

Accepted Answer

Simple squamous epithelium

Question 5

A biopsy from the urinary bladder reveals an epithelium with multiple layers of rounded cells that flatten when stretched. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 6

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

Accepted Answer

Cartilage lacks a direct blood supply and often heals by fibrosis.

Question 7

Which of the following is a key difference between exocrine and endocrine glands?

Accepted Answer

Exocrine glands release their products onto epithelial surfaces via ducts.

Question 8

A tissue sample shows cells with striations, multiple nuclei, and voluntary control. Which tissue is this?

Accepted Answer

Skeletal muscle

Question 9

Which connective tissue type is specialized for energy storage, insulation, and shock absorption?

Accepted Answer

Adipose tissue

Question 10

Which of the following best describes the process of tissue repair by fibrosis?

Accepted Answer

Fibroblasts produce collagen to fill the defect, resulting in scar tissue.

Question 11

Which of the following best describes the function of gap junctions in cardiac muscle tissue?

Accepted Answer

They allow ions and small molecules to pass directly between cells, enabling coordinated contraction.

Question 12

Which of the following is a function of reticular connective tissue?

Accepted Answer

Forming the framework for lymphatic organs

Question 13

A patient has a mutation that prevents the formation of elastic fibers in the ECM. Which organ system would be most affected?

Accepted Answer

Cardiovascular system (especially large arteries)

Question 14

Which of the following best describes the main function of neuroglial cells in nervous tissue?

Accepted Answer

Supporting, protecting, and nourishing neurons

Question 15

Which of the following is true regarding the basement membrane in epithelial tissues?

Accepted Answer

It provides structural support and anchors the epithelium to underlying connective tissue.

Question 16

Which of the following best explains why cardiac muscle tissue heals primarily by fibrosis rather than regeneration?

Accepted Answer

Cardiac muscle cells are amitotic and cannot divide to replace lost cells.

Question 17

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

Accepted Answer

All cells reach the basement membrane, but nuclei are at different levels.

Question 18

Which of the following best describes the main function of hyaline cartilage at the ends of long bones?

Accepted Answer

Providing flexible support and reducing friction

Question 19

Which of the following is a correct pairing of gland type and secretion method?

Accepted Answer

Apocrine glands: release product with a portion of the cytoplasm

Question 20

A patient with a severe burn loses the protective barrier of the skin. Which type of membrane has been compromised?

Accepted Answer

Cutaneous membrane
