Canaliculi are tiny, microscopic channels found in bone tissue. They connect osteocytes, which are the bone cells, allowing them to communicate and share nutrients. This network is essential for maintaining healthy bone structure and function. These channels are part of the larger bone matrix, which includes minerals like calcium and phosphorus. The presence of canaliculi helps ensure that the bone remains strong and can adapt to stress, making them crucial for the overall health of the skeletal system.
