Part of the extracellular matrix secreted by osteocytes. (Ans. B)

Explanation:

Cells which are present on bones are known as osteocytes. Bone is composed of extracellular matrix, and cells. There are three types of cells which are present in the bones:

1) Osteoprogenitor cells.

2) Osteoblast.

3) Osteocyte.

Extracellular matrix is composed of organic matrix consisting glycoproteins, proteoglycans, osteocalcin also known as calcium binding proteins, and osteonectin which anchors bone mineral to collagen.
