Question 4

Which of the following is TRUE regarding cartilage?

Accepted Answer

Its matrix is secreted by chondrocytes and contains chondroitin sulfate and hyaluronic acid.

Question 5

Which connective tissue fiber type provides the greatest tensile strength?

Question 9

A patient develops a scar in the heart after a myocardial infarction. What is the most likely consequence of this fibrosis?

Question 10

Which of the following best describes the composition of the extracellular matrix (ECM) in connective tissue?

Accepted Answer

It is made up of ground substance and fibers.

Question 11

Which germ layer gives rise to muscle and connective tissues during embryonic development?

Accepted Answer

Cutaneous membrane (skin)

Question 17

During tissue repair, which process involves connective tissue replacing destroyed tissue, resulting in loss of original function?

Accepted Answer

Fibrosis

Question 18

Which of the following best describes the role of mast cells in connective tissue?

Accepted Answer

They initiate local inflammatory responses against foreign microorganisms.

Question 19

Which of the following equations correctly represents the relationship between the tensile strength ($$T) of a $$connective tissue and the amount of collagen fibers ($$C) $$present?

Accepted Answer

$$T = k \cdot C$$

Question 20
