Question 1

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

Accepted Answer

They prevent the passage of water and solutes between cells, maintaining compartmentalization.

Question 2

A patient presents with a disorder that affects the production of chondroitin sulfates. Which tissue is most likely to be compromised?

Accepted Answer

Cartilage tissue

Question 3

Which of the following statements about epithelial tissue is TRUE?

Accepted Answer

Epithelial cells are replaced by continual division of stem cells located near the basement membrane.

Question 4

Which type of gland releases its secretions by the bursting of cells, resulting in cell death?

Accepted Answer

Holocrine gland

Question 5

A biopsy of a patient’s tissue reveals cells with many mitochondria, a high degree of vascularization, and the ability to generate heat. Which type of tissue is most likely present?

Accepted Answer

Brown adipose tissue

Question 6

Which connective tissue fiber is most abundant in tendons and ligaments, and resists force in one direction?

Accepted Answer

Collagen fibers

Question 7

Which of the following best explains why cartilage injuries heal slowly?

Accepted Answer

Chondrocytes produce antiangiogenesis factor, making cartilage avascular and limiting nutrient supply.

Question 8

Which membrane lines body cavities that do NOT open to the outside and reduces friction between organs?

Accepted Answer

Serous membrane

Question 9

A patient suffers trauma to the skin, resulting in inflammation. Which cell type is primarily responsible for releasing histamine and heparin to stimulate the inflammatory response?

Accepted Answer

Mast cells

Question 10

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

Accepted Answer

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

Question 11

Which of the following is a function of areolar tissue?

Accepted Answer

Holds capillary beds and supports epithelia

Question 12

Which of the following best describes the difference between simple and stratified epithelium?

Accepted Answer

Simple epithelium consists of a single layer of cells, while stratified epithelium has multiple layers.

Question 13

Which of the following cell types is responsible for producing antibodies in connective tissue?

Accepted Answer

Plasma cells (derived from lymphocytes)

Question 14

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

Accepted Answer

They allow rapid communication and coordinate contractions by permitting the passage of ions.

Question 15

Which of the following tissues is most likely to regenerate poorly after injury?

Accepted Answer

Cardiac muscle tissue

Question 16

A patient is diagnosed with a disease that causes the basement membrane to lose strength. Which layer is most likely affected?

Accepted Answer

Reticular lamina

Question 17

Which of the following best describes the function of the lamina propria in mucous membranes?

Accepted Answer

It is areolar tissue that supports the epithelium and facilitates absorption and secretion.

Question 18

Which of the following best explains why the skin (cutaneous membrane) is relatively waterproof?

Accepted Answer

It is composed of stratified squamous epithelium with keratin.

Question 19

Which equation best represents the rate of heat loss ($$Q) $$through adipose tissue, assuming white fat acts as an insulator and heat loss is inversely proportional to the thickness ($$d) of $$the adipose layer?

Accepted Answer

$$Q = \frac{k}{d}$$

Question 20

Which of the following is TRUE regarding the effects of aging on tissue structure?

Accepted Answer

Aging leads to thinner epithelia, fragile connective tissues, and increased risk of cardiovascular disease.
