Accepted Answer

Cardiac muscle

Question 3

Which characteristic is unique to epithelial tissue compared to other tissue types?

Accepted Answer

Has a free (apical) surface exposed to the environment or organ cavity

Question 4

Which type of cell junction is primarily responsible for preventing the leakage of material between epithelial cells?

Accepted Answer

Tight junctions

Question 5

A tissue sample is observed to have cells with microvilli on their apical surface. What is the most likely function of this tissue?

Accepted Answer

Absorption

Question 6

Which connective tissue fiber type provides the greatest tensile strength to tissues?

Accepted Answer

Collagen fibers

Question 7

A genetic mutation in the FBN1 gene affects the production of fibrillin, leading to weakened connective tissue. Which syndrome is most likely present?

Accepted Answer

Marfan syndrome

Question 8

Which of the following best explains why epithelial tissue is avascular?

Accepted Answer

It receives nourishment by diffusion from underlying connective tissue.

Question 9

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

Accepted Answer

Stratified squamous epithelium

Question 10

Which of the following is a function of the basement membrane in epithelial tissue?

Accepted Answer

It reinforces the epithelial sheet and defines the boundary with connective tissue.

Question 11

A gland releases its secretion by exocytosis without damaging the secreting cell. What type of gland is this?

Accepted Answer

Merocrine gland

Question 12

Which connective tissue type is most likely to be found in tendons and ligaments, providing resistance to tension in one direction?

Accepted Answer

Dense regular connective tissue

Question 13

Which of the following best describes the process of tissue repair after injury?

Accepted Answer

Regeneration replaces lost cells, while fibrosis forms scar tissue.

Question 14

Which of the following equations best represents the relationship between the number of cell layers ($$n) $$and the type of epithelial tissue?

Accepted Answer

$$n = 1$$ ightarrow 	ext{Simple epithelium}$

Question 15

A patient with Marfan syndrome is at increased risk for which of the following complications due to defective connective tissue?

Accepted Answer

Aortic aneurysm

Question 16

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

Accepted Answer

They form fine, branched networks that support free blood cells.

Question 17

Which type of epithelial tissue lines the inside of blood vessels, providing a slick surface to reduce friction?

Accepted Answer

Endothelium (simple squamous epithelium)

Question 18

Which of the following is a real-world consequence of the avascular nature of cartilage?

Accepted Answer

Cartilage heals slowly after injury due to limited blood supply.

Question 19

Which equation best represents the relationship between ground substance viscosity ($$\eta) $$and proteoglycan concentration ($$[P]) in $$connective tissue?

Accepted Answer

$$\eta \propto [P]$$

Question 20

Which of the following best explains why stratified epithelial tissue is found in areas subject to high abrasion?

Accepted Answer

Multiple layers provide increased protection against physical and chemical stress.
