$$\text{Rate of Repair} \propto \text{Vascularity}$$

Question 1

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

Accepted Answer

Transmitting electrical impulses

Question 2

All connective tissues share a common embryonic origin. From which tissue do they arise?

Accepted Answer

Mesenchyme

Question 3

Cartilage is avascular, while bone is highly vascularized. What is the consequence of this difference for tissue repair?

Accepted Answer

Cartilage heals slowly due to lack of blood supply

Question 4

Which connective tissue cell type is responsible for actively secreting ground substance and ECM fibers during growth?

Accepted Answer

Blast cells (e.g., fibroblasts, chondroblasts, osteoblasts)

Question 5

A patient suffers a ligament injury. Which type of connective tissue is most likely affected?

Accepted Answer

Dense regular connective tissue

Question 6

Which connective tissue is most widely distributed and acts as universal packing material between other tissues?

Accepted Answer

Areolar connective tissue

Question 7

Which of the following best describes the composition of ground substance in connective tissue?

Accepted Answer

Unstructured gel-like material containing interstitial fluid, cell adhesion proteins, proteoglycans, and water

Question 8

Which type of connective tissue fiber provides the greatest tensile strength?

Accepted Answer

Collagen fibers

Question 9

A patient with a sports injury has slow healing in their knee cartilage. What property of cartilage explains this?

Accepted Answer

Cartilage is avascular and receives nutrients by diffusion

Question 10

Which connective tissue type is specialized for storing nutrients and providing insulation?

Accepted Answer

Adipose tissue

Question 11

Which of the following equations best represents the relationship between tissue repair and blood supply?

Accepted Answer

$$	ext{Rate of Repair} \propto 	ext{Vascularity}$$

Question 12

Which connective tissue type forms the stroma that supports blood cells in lymph nodes, spleen, and bone marrow?

Accepted Answer

Reticular connective tissue

Question 13

Which of the following is TRUE about blood as a connective tissue?

Accepted Answer

Blood is a fluid connective tissue with plasma as its matrix and functions in transport

Question 14

Which muscle tissue type is striated, voluntary, and contains multiple nuclei per cell?

Accepted Answer

Skeletal muscle

Question 15

Which covering and lining membrane is composed of keratinized stratified squamous epithelium attached to a thick layer of connective tissue?

Accepted Answer

Cutaneous membrane (skin)

Question 16

During tissue repair, which process results in the loss of original function due to replacement by connective tissue?

Accepted Answer

Fibrosis

Question 17

Which tissue type has virtually no functional regenerative capacity?

Accepted Answer

Cardiac muscle and nervous tissue

Question 18

A patient develops scar tissue in the heart after a myocardial infarction. What is a possible consequence?

Accepted Answer

Impaired contractile function and reduced volume capacity

Question 19

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

Accepted Answer

Initiate local inflammatory response against foreign microorganisms

Question 20

Which equation best represents the relationship between the amount of water trapped in ground substance and its viscosity?

Accepted Answer

$$	ext{Viscosity} \propto 	ext{Water Content}$$
