Question 1

Which of the following best describes the main structural difference between loose connective tissue and dense regular connective tissue?

Accepted Answer

Loose connective tissue contains more ground substance and fewer, less organized fibers compared to dense regular connective tissue.

Question 2

A patient presents with a genetic disorder in which their tendons are easily torn and heal very slowly. Which property of dense regular connective tissue best explains this slow healing?

Accepted Answer

Dense regular connective tissue has a limited blood supply, which slows healing.

Question 3

Which of the following cell types is responsible for producing the extracellular matrix in cartilage?

Accepted Answer

Chondroblasts

Question 4

Which connective tissue type is most involved in the first line of defense against invading microorganisms under the epithelium?

Accepted Answer

Areolar connective tissue

Question 5

Which of the following best explains why brown adipose tissue is more abundant in infants than adults?

Accepted Answer

Brown adipose tissue generates heat to help maintain body temperature in infants who cannot shiver effectively.

Question 6

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

Accepted Answer

Collagen fibers

Question 7

A mutation causes the ground substance in a patient’s cartilage to become less hydrated. Which property of cartilage would be most affected?

Accepted Answer

Its ability to spring back after compression

Question 8

Which connective tissue type forms the internal framework (stroma) of lymphoid organs such as the spleen and lymph nodes?

Accepted Answer

Reticular connective tissue

Question 9

Which of the following best describes the embryonic origin of all connective tissues?

Accepted Answer

They all originate from mesenchyme.

Question 10

Which of the following is a correct pairing of connective tissue cell type and its primary function?

Accepted Answer

Osteoclast – breaking down bone matrix

Question 11

A patient with fibrodysplasia ossificans progressiva (FOP) experiences progressive replacement of fibrous tissues with bone. Which tissues are most likely to be affected first?

Accepted Answer

Tendons, ligaments, and muscles

Question 12

Which of the following best explains why blood is classified as a connective tissue?

Accepted Answer

Blood develops from mesenchyme and consists of cells surrounded by a nonliving matrix (plasma).

Question 13

Which connective tissue type is best suited to resist tension from multiple directions, such as in the dermis of the skin?

Accepted Answer

Dense irregular connective tissue

Question 14

Which of the following is NOT a function of adipose tissue?

Accepted Answer

Forming the internal skeleton of lymphoid organs

Question 15

Which of the following best describes the role of elastic fibers in connective tissue?

Accepted Answer

They allow tissues to stretch and recoil.

Question 16

Which of the following statements about the extracellular matrix (ECM) of connective tissue is correct?

Accepted Answer

The ECM is the non-living component that largely determines the tissue’s properties.

Question 17

Which connective tissue cell type is primarily responsible for immune defense within areolar connective tissue?

Accepted Answer

Macrophage

Question 18

A tissue sample contains abundant collagen fibers running parallel to each other and very few cells. Which tissue is this most likely to be?

Accepted Answer

Dense regular connective tissue

Question 19

Which of the following best explains why plasma is considered the non-living matrix of blood?

Accepted Answer

Plasma is the fluid component that surrounds blood cells and is not produced by the blood cells themselves.

Question 20

Which of the following equations best represents the relationship between the components of connective tissue?

Accepted Answer

$$	ext{Connective Tissue} = 	ext{Cells} + 	ext{Extracellular Matrix}$$
