Bone-forming cells are called __ osteons osteoclasts osteocytes osteoblasts osteogenic (osteoprogenitor cells

## Step 1<br />The question asks for the type of cells that are responsible for forming bones. The options provided are osteons, osteoclasts, osteocytes, osteoblasts, and osteogenic (osteoprogenitor) cells.<br /><br />## Step 2<br />Osteons are not cells, but rather structural units of compact bone. They are not involved in the formation of bones.<br /><br />## Step 3<br />Osteoclasts are cells that break down bone tissue. This process is known as bone resorption. They are not involved in the formation of bones.<br /><br />## Step 4<br />Osteocytes are mature bone cells that originate from osteoblasts. They are involved in the maintenance of bone tissue, but not in the formation of bones.<br /><br />## Step 5<br />Osteoblasts are the cells responsible for bone formation. They synthesize and secrete the bone matrix, which is a mixture of collagen and other proteins. This process is known as bone formation.<br /><br />## Step 6<br />Osteogenic (osteoprogenitor) cells are stem cells that can differentiate into osteoblasts. They are not directly involved in the formation of bones.
