Osteocytes are bone cells that sit within chambers called lacuna. Lacuna are connective via tine canals called canaliculi and form concentric circles around a central haversian canal. This coloring worksheet may help with your understanding of these relationships.
It can be very difficult to develop a mental map of all of these structures. Imagine the lacuna is a space holding the osteocyte and your fingers are the canaliculi. If you have friends, you can model multiple osteocytes and the circular arrangement of the lamella, as shown below.
