Q: Which formula correctly represents the relationship between the components of connective tissue?

$$\text{Connective Tissue} = \text{Specialized Cells} + \text{Extracellular Protein Fibers} + \text{Fluid (Matrix)}$$

Question 1

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

Accepted Answer

Dense regular connective tissue has collagen fibers arranged in parallel bundles, while dense irregular connective tissue has collagen fibers arranged in random, interwoven patterns.

Question 2

A patient presents with a joint injury that requires extra flexibility for healing. Which type of connective tissue would be most beneficial in this scenario?

Accepted Answer

Elastic connective tissue

Question 3

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

Accepted Answer

Initiating voluntary muscle contraction

Question 4

Which formula correctly represents the relationship between the components of connective tissue?

Accepted Answer

$$	ext{Connective Tissue} = 	ext{Specialized Cells} + 	ext{Extracellular Protein Fibers} + 	ext{Fluid (Matrix)}$$

Question 5

Which connective tissue type is most likely to be found wrapping and cushioning organs, and why?

Accepted Answer

Areolar tissue, because it contains widely spaced cells and a lot of open space for packing and cushioning.

Question 6

A biopsy of tissue from the spleen reveals a network of thin fibers and numerous immune cells. Which connective tissue is most likely present?

Accepted Answer

Reticular connective tissue

Question 7

Which of the following statements about cartilage is TRUE?

Accepted Answer

Cartilage is avascular and all nutrients come from the perichondrium.

Question 8

Which type of cartilage is most commonly found at the ends of bones and in the soft part of the nose, and what is its primary function?

Accepted Answer

Hyaline cartilage; provides pliable support and reduces friction during joint movement.

Question 9

Which of the following best explains why osseous tissue (bone) is considered a supporting connective tissue?

Accepted Answer

It contains a solid matrix of calcium phosphate and calcium carbonate, providing structural support and protection.

Question 10

Which of the following is a correct description of the matrix in blood?

Accepted Answer

The matrix is plasma, which does not form insoluble fibers.

Question 11

A patient with chronic sun exposure develops reduced flexibility in their skin. Which connective tissue change is most likely responsible?

Accepted Answer

Loss of elasticity in elastic connective tissue due to damage to elastic fibers.

Question 12

Which connective tissue type is most responsible for resisting tension in tendons and ligaments?

Accepted Answer

Dense regular connective tissue

Question 13

Which of the following equations best represents the relationship between ground substance, fibers, and cells in loose connective tissue?

Accepted Answer

$$	ext{Loose Connective Tissue} = 	ext{More Ground Substance} + 	ext{Fewer Fibers} + 	ext{More Cells}$$

Question 14

Which specialized connective tissue is involved in blood clotting and fighting infection?

Accepted Answer

Blood

Question 15

Which connective tissue type is most likely to be found in the internal framework of lymph nodes and bone marrow?

Accepted Answer

Reticular connective tissue

Question 16

A tissue sample contains mostly cell-adipocytes and is responsible for fat storage and padding/protection. Which tissue is this?

Accepted Answer

Adipose tissue

Question 17

Which of the following is a function of fibroblasts in connective tissue?

Accepted Answer

Producing extracellular protein fibers such as collagen and elastic fibers

Question 18

Which connective tissue type is most likely to be found in the walls of arteries, providing flexibility and resilience?

Accepted Answer

Elastic connective tissue

Question 19

Which of the following best explains why inflammation leads to swelling in areolar tissue?

Accepted Answer

Areolar tissue holds large amounts of ground substance, which draws fluid into the tissue during inflammation.

Question 20

Which of the following is TRUE regarding the matrix of lymph?

Accepted Answer

The matrix of lymph is interstitial fluid.
