Bone canaliculi are microscopic canals between the lacunae of ossified bone. The radiating processes of the osteocytes (called filopodia) project into these canals. These cytoplasmic processes are joined together by gap junctions. ... In cartilage, the lacunae and hence, the chondrocytes, are isolated from each other.
