Question 1

Which of the following best describes the primary function of tight junctions in epithelial tissue?

Accepted Answer

They prevent the passage of substances between adjacent epithelial cells by forming a barrier.

Question 2

A patient presents with a genetic disorder that impairs the function of connexons. Which tissue function is most likely to be affected?

Accepted Answer

Coordinated contraction of cardiac muscle

Question 3

Which type of epithelial tissue is best suited for areas of the body subject to abrasion, such as the skin and oral cavity?

Accepted Answer

Stratified squamous epithelium

Question 4

Which of the following is a characteristic of all epithelial tissues?

Accepted Answer

They are capable of regeneration.

Question 5

A gland that releases its product by shedding the apical portion of the cell along with the secretion is classified as which type of gland?

Accepted Answer

Apocrine gland

Question 6

Which connective tissue fiber type is most responsible for providing tensile strength in tendons and ligaments?

Accepted Answer

Collagen fibers

Question 7

A biopsy of a patient’s tissue reveals a single layer of tall, narrow cells with nuclei aligned near the base. Which tissue type is most likely observed?

Accepted Answer

Simple columnar epithelium

Question 8

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

Accepted Answer

Cartilage is avascular, so nutrients and waste removal rely on slow diffusion.

Question 9

Which membrane type lines body cavities that do NOT open to the exterior and produces a fluid to reduce friction between organs?

Accepted Answer

Serous membrane

Question 10

A patient with a burn injury to the skin is at increased risk of dehydration and infection. Which property of the cutaneous membrane is most responsible for this protective function?

Accepted Answer

It is thick, keratinized, and water-resistant.

Question 11

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

Accepted Answer

Formation of scar tissue that does not restore original function

Question 12

Which of the following equations best represents the relationship between tissue growth and cell number?

Accepted Answer

$$N_{final} = N_{initial} + \Delta N$$

Question 13

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

Accepted Answer

Serves as a passageway for nerves and blood vessels beneath epithelia

Question 14

A patient with a genetic defect in desmosome formation would most likely experience which of the following symptoms?

Accepted Answer

Fragile skin that blisters easily under mechanical stress

Question 15

Which of the following best explains why skeletal muscle cells are multinucleated?

Accepted Answer

They are formed by the fusion of multiple myoblasts during development.

Question 16

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

Accepted Answer

Endocrine glands lack ducts and release hormones into interstitial fluid.

Question 17

Which of the following best describes the function of neuroglia in nervous tissue?

Accepted Answer

Support and protect neurons

Question 18

A tissue sample shows cells embedded in a calcified matrix arranged in concentric rings around a central canal. Which tissue is this?

Accepted Answer

Compact bone

Question 19

Which of the following best describes the process of apoptosis?

Accepted Answer

Programmed cell death as part of normal development

Question 20

Which of the following is a likely consequence of aging on tissue structure and function?

Accepted Answer

Thinning of epithelia and increased bone brittleness
