Accepted Answer

Bone (osseous tissue)

Question 4

A patient suffers a deep cut that heals with a visible scar. Which tissue repair process is primarily responsible for this outcome?

Accepted Answer

Fibrosis by dense connective tissue

Question 5

Which of the following best explains why cartilage heals more slowly than bone after injury?

Question 8

Which of the following best describes the extracellular matrix of connective tissue?

Accepted Answer

A nonliving material that surrounds living cells, composed of ground substance and fibers

Question 9

A tissue sample shows cells with large lipid droplets pushing the nucleus to the side. Which tissue is this, and what is its primary function?

Accepted Answer

Accepted Answer

Connective tissue

Question 12

Which of the following best explains why epithelial tissues are able to regenerate quickly after injury?
