D) Osteoblasts produce the collagen fibers of bone.

Question

Quizplus · Accepted Answer

Osteoblasts produce the collagen fibers of bone but they do not produce bone's hydroxyapatite crystals. They simply allow hydroxyapatite to be deposited. Calcium phosphate is dissolved in body fluids and blood. If it is highly concentrated, it will settle out of solution to form crystals. Most body tissues make a chemical that prevents calcium phosphate crystals from forming. This prevents tissues like those in the muscles, liver, and eyes from calcifying.
