Question 6

Which connective tissue cell type is primarily responsible for producing collagen fibers and ground substance?

Accepted Answer

Fibroblasts

Question 7

Which of the following best describes the function of gap junctions in cardiac muscle tissue?

Question 14

Which of the following best explains why bone tissue is highly vascularized compared to cartilage?

Accepted Answer

Bone tissue contains canaliculi that allow nutrients to reach osteocytes.

Question 15
