Canaliculi are tiny channels found in bone tissue. They play a crucial role in the communication and nutrient exchange between bone cells, known as osteocytes. These microscopic structures connect the lacunae, which are the small spaces where osteocytes reside, to each other and to larger channels called Haversian canals.
The primary function of canaliculi is to facilitate the transfer of nutrients and waste products between the blood supply in the Haversian canals and the osteocytes. This network ensures that even the most deeply embedded bone cells receive the necessary nutrients and oxygen for their survival and function. Additionally, canaliculi help in the maintenance and repair of bone tissue by allowing osteocytes to communicate and coordinate their activities.
