Question

which of the following is not found in the matrix of cartilage but is found in bone: living cells, lacunae, blood vessels, organic fibers. question 2 (1 point) the reason that intervertebral discs exhibit a large amount of tensile strength, which allows them to absorb shock, is because they possess __________. hydroxyapatite crystals, collagen fibers, reticular fibers, elastic fibers

Explanation:

1. Cartilage matrix lacks blood - vessels while bone matrix has them. Living cells, lacunae, and organic fibers are present in both.
2. Collagen fibers give intervertebral discs high tensile strength for shock - absorption. Hydroxyapatite crystals are related to bone hardness, reticular fibers provide a supportive framework, and elastic fibers give elasticity.

Answer:

1. C. blood vessels
2. B. collagen fibers
