A: Bones are hard structures that are . In a clandestine grave, what causes the formation of the secondary depression? Because the matrix is mineralized (rather than aqueous), nutrients and waste cannot diffuse through the matrix. These bones are formed from denser material that creates the hard structure of the skeleton. The dynamic nature of bone means that new tissue is constantly formed, and old, injured, or unnecessary bone is dissolved for repair or for calcium release. compact bone, also called cortical bone, dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells. As seen in the image below, compact bone forms the cortex, or hard outer shell of most bones in the body. The cellular layer is adjacent to the cortical bone and is covered by an outer fibrous layer of dense irregular connective tissue (see Figure 6.3.4a).
