Question 1

Which of the following best explains why epithelial tissues are avascular but highly regenerative?

Accepted Answer

Epithelial tissues rely on diffusion from underlying connective tissue for nutrients and have a high rate of mitosis to replace damaged cells.

Question 2

A patient suffers a severe abrasion to the skin. Which type of epithelial tissue is most likely to be involved in protecting the underlying tissues in this scenario?

Accepted Answer

Stratified squamous epithelium

Question 3

Which of the following best describes the function of the basement membrane in epithelial tissues?

Accepted Answer

It attaches the epithelium to underlying connective tissue and resists stretching and tearing.

Question 4

Which glandular secretion method involves the product accumulating in the cell until the cell ruptures, releasing its contents?

Accepted Answer

Holocrine

Question 5

A biopsy of a patient's trachea reveals a single layer of cells of varying heights with nuclei at different levels and cilia on the surface. Which type of epithelium is this?

Accepted Answer

Pseudostratified ciliated columnar epithelium

Question 6

Which connective tissue fiber type is primarily responsible for providing high tensile strength and preventing tearing?

Accepted Answer

Collagen fibers

Question 7

A patient with a ruptured intervertebral disc is experiencing pain due to compression. Which type of connective tissue is most likely damaged?

Accepted Answer

Fibrocartilage

Question 8

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

Accepted Answer

Endocrine glands are ductless and secrete hormones into the blood or lymph; exocrine glands secrete products onto body surfaces or into body cavities via ducts.

Question 9

Which of the following connective tissues is specialized for energy storage, insulation, and protection of organs?

Accepted Answer

Adipose connective tissue

Question 10

A patient is diagnosed with a condition affecting the lamina propria. Which type of membrane is most likely involved?

Accepted Answer

Mucous membrane

Question 11

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

Accepted Answer

Cartilage is avascular, so it lacks direct blood supply for nutrient delivery and waste removal.

Question 12

Which muscle tissue type is characterized by striations, branching cells, and is found only in the heart?

Accepted Answer

Cardiac muscle

Question 13

During tissue repair, which process involves the formation of granulation tissue and the activity of macrophages and fibroblasts?

Accepted Answer

Organization (restoration of blood supply)

Question 14

Which of the following best describes the main function of reticular fibers in connective tissue?

Accepted Answer

Form delicate networks that support soft tissues and blood vessels

Question 15

A tissue sample shows cells with microvilli, a single layer of square-shaped cells, and round nuclei. Which tissue is this most likely to be?

Accepted Answer

Simple cuboidal epithelium

Question 16

Which of the following equations best represents the relationship between the rate of diffusion ($$R$$), surface area ($$A$$), and membrane thickness ($$d) in $$simple squamous epithelium?

Accepted Answer

$$R = \frac{A}{d}$$

Question 17

Which of the following best explains why dense regular connective tissue is well-suited for tendons and ligaments?

Accepted Answer

It contains parallel collagen fibers that provide great tensile strength in one direction.

Question 18

A patient with liver damage is unable to produce sufficient plasma proteins. Which tissue type is primarily responsible for this function?

Accepted Answer

Epithelial tissue (glandular epithelium)

Question 19

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

Accepted Answer

Proliferation of fibroblasts leading to scar tissue formation

Question 20

Which of the following tissues has the poorest capacity for regeneration after injury?

Accepted Answer

Cardiac muscle tissue
