Osteons, also known as Haversian systems, are structural units of compact bone and consist of concentric layers of bone matrix surrounding a central canal. Osteocytes, on the other hand, are mature bone cells that reside within small cavities called lacunae and are embedded within the bone matrix. While osteocytes are found within osteons, they do not constitute osteons themselves. Instead, they play a crucial role in maintaining the bone tissue and communicating with other bone cells.
