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

Question 6

Which connective tissue fiber type provides the greatest tensile strength?

Accepted Answer

Collagen fibers

Question 7

Which cell type is responsible for actively secreting ground substance and ECM fibers in bone tissue?

Accepted Answer

Osteoblasts

Question 8

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

Accepted Answer

Areolar connective tissue

Question 9

Which of the following best describes the matrix of hyaline cartilage?

Accepted Answer

Gel-like ground substance with collagen fibers

Question 10

A patient with a heart attack develops scar tissue in the heart. What is the likely consequence?

Accepted Answer

Impaired function due to loss of contractility and volume capacity

Question 11

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

Accepted Answer

Reticular connective tissue

Question 12

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

Question 14

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

Accepted Answer

Cutaneous membrane

Question 15

During tissue repair, which process results in the replacement of destroyed tissue with the same kind of tissue, restoring original function?

Accepted Answer

Regeneration

Question 16

Which of the following tissues has virtually no functional regenerative capacity?

Accepted Answer

Cardiac muscle

Question 17

Which equation best represents the relationship between the volume of water trapped in ground substance and the viscosity of connective tissue?

Accepted Answer

$$ V_{water} \propto \eta_{viscosity} $$

Question 18

Which cell type initiates local inflammatory responses against foreign microorganisms in connective tissue?

Accepted Answer

Mast cells

Question 19

Which of the following best describes the role of fibroblasts in connective tissue repair?

Accepted Answer

They produce collagen fibers to bridge the gap during organization

Question 20

A patient has a wound that heals with visible scar tissue and loss of original function. Which process has occurred?

Accepted Answer
