Which term describes the outer layer of bone known as the cortical bone?

Explanation:
The outer, dense layer of bone is cortical bone, also called compact bone. It forms a hard shell around the bone, providing most of the strength and rigidity. Osteoid is the organic matrix produced by osteoblasts before mineralization, not the outer layer. The periosteum is the fibrous membrane covering the bone, again not the bone tissue itself. The combining form chondr/o means cartilage. So cortical bone is the term that describes the outer layer.
