Question 1

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

Accepted Answer

ECM provides strength to resist tensile and compressive forces, directs cells to their proper positions, and regulates cell development, mitotic activity, and survival.

Question 2

A patient presents with a skin injury. Which type of epithelial tissue is most likely to be involved in providing protection against mechanical stress and dehydration?

Accepted Answer

Keratinized stratified squamous epithelium

Question 3

Which cell junction type is primarily responsible for preventing substances from passing between cells, thus maintaining the integrity of epithelial barriers?

Accepted Answer

Tight junctions

Question 4

A gland that releases its products directly into the bloodstream without the use of ducts is classified as:

Accepted Answer

Endocrine gland

Question 5

Which protein fiber found in the ECM is most responsible for providing tissues with resistance to tension and pressure?

Accepted Answer

Collagen fibers

Question 6

A biopsy of a patient’s tendon reveals parallel bundles of fibers with very little ground substance. Which type of connective tissue is this?

Accepted Answer

Dense regular connective tissue

Question 7

Which of the following equations best represents the relationship between the number of cell layers ($$n) $$and the permeability ($$P) of an $$epithelial tissue, assuming permeability decreases exponentially with more layers?

Accepted Answer

$$P = P_0$ \cdot e$$^{-kn}$$

Question 8

Which tissue type is most likely to undergo fibrosis rather than regeneration after injury, and why?

Accepted Answer

Cartilage, because its resident cells have limited capacity for mitosis.

Question 9

A patient with liver damage is found to have excessive scar tissue formation. Which process is responsible for this outcome?

Accepted Answer

Fibrosis

Question 10

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

Accepted Answer

They divide by mitosis and support neurons structurally and functionally.

Question 11

Which equation would you use to calculate the total surface area ($$A) $$available for absorption in the small intestine, given $$n$$ microvilli per cell, $$m$$ cells per unit area, and each microvillus has surface area $$a$$?

Accepted Answer

$$A = n \cdot m \cdot a$$

Question 12

Which muscle tissue type is under voluntary control and is composed of multinucleated, striated cells?

Accepted Answer

Skeletal muscle tissue

Question 13

A patient is diagnosed with a disorder affecting the synovial membrane. Which joint function is most likely to be impaired?

Accepted Answer

Lubrication of freely movable joints

Question 14

Which of the following is a major function of adipose tissue besides fat storage?

Accepted Answer

Shock absorption and insulation

Question 15

Which equation best describes the rate of diffusion ($$R) of $$oxygen across a simple squamous epithelium, given permeability ($$P$$), surface area ($$A$$), and concentration difference ($$\Delta C$$)?

Accepted Answer

$$R = P \cdot A \cdot \Delta C$$

Question 16

Which of the following best explains why cartilage is limited in thickness compared to other tissues?

Accepted Answer

Cartilage is avascular, so oxygen and nutrients must diffuse through the ECM, limiting thickness.

Question 17

Which membrane type lines body cavities that do NOT open to the outside of the body and produces fluid to reduce friction?

Accepted Answer

Serous membrane

Question 18

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

Accepted Answer

Allowing ions to pass directly between cells, enabling synchronized contraction of the heart muscle

Question 19

Which tissue repair mechanism is most likely to restore full function after injury to the lining of the digestive tract?

Accepted Answer

Regeneration

Question 20

Which of the following best describes the structural arrangement and function of transitional epithelium in the urinary bladder?

Accepted Answer

Multiple layers of dome-shaped cells that flatten when stretched, allowing the bladder to expand
