Final answer:
The area between neighboring osteons contains 'interstitial lamellae' with lacunae housing osteocytes and canaliculi as remnants of older osteons. These contribute to bone support and participate in nutrient transport and waste removal.
Step-by-step explanation:
Areas between neighboring osteons contain lamellae called interstitial lamellae, which also have lacunae with osteocytes and canaliculi; these are fragments of older osteons that have been partially destroyed during bone rebuilding or growth. Osteocytes are located inside spaces called lacunae and obtain nutrients via canaliculi, which connect to other lacunae and eventually lead to the central canal. This canal is a component of the osteon or Haversian system, which also includes blood vessels, nerves, and lymphatic vessels. The central canal is surrounded by concentric rings of calcified matrix called lamellae, and the boundary of an osteon is referred to as the cement line.Spongy bone, also known as cancellous bone, differs from compact bone in that it contains a lattice-like network of matrix spikes called trabeculae and does not feature the concentric lamellae arrangement. This trabeculated structure helps to make bones lighter and provides space for red marrow, where hematopoiesis occurs.Compact bone's structure aids in the support and protection of the bones, while the spongy bone contributes to the lightweight nature of the skeletal system and the creation of blood cells within the marrow.
