WebbAnswer and Explanation: 1. Cells that secrete the organic components of the bone matrix are called osteoblasts. These cells are derived from osteoprogenitor cells. These are cuboidal or polygonal mononuclear cell lining the bone surface and closing cone of resorption canals. WebbSome of these cells will differentiate into capillaries, ... The osteoblasts secrete osteoid, uncalcified matrix, which calcifies (hardens) within a few days as mineral salts are deposited on it, thereby entrapping the osteoblasts within. Once entrapped, the osteoblasts become osteocytes (b).

WebbCells that are involved in growing bone: Osteoprogenitor cells are the 'stem' cells of bone, and are the source of new osteoblasts. Osteoblasts, lining the surface of bone, secrete collagen and the organic matrix of bone (osteoid), which becomes calcified soon after it has been deposited. WebbOsteoblasts are cells that form bone tissue. Osteoblasts can synthesize and secrete bone matrix and participate in the mineralization of bone to regulate the balance of calcium and phosphate ions in developing bone. Osteoblasts are derived from osteoprogenitor cells.
