Question

Quizplus · Accepted Answer

Collagen fibers and calcium salts are major components of the extracellular matrix of bone, which surrounds and supports osteocytes. These substances are not part of the plasma membrane or extensions of the endoplasmic reticulum of osteocytes. They are also not simply deposited by the circulatory system, but are actively synthesized and secreted by osteoblasts, which are immature bone cells.
