The osteocytes in their lacunae are found between the rings of matrix. The central canal (Haversian canal or osteonic canal) is found in the center of the osteon. You will see other canals that run horizontally through the compact bone. These are perforating (Volkmann’s) canals. What is the function of this system of canals running through bony tissue?
The system of canals running through bony tissue, including the central canal (Haversian canal) and the perforating (Volkmann's) canals, serve several functions:
1. Blood supply: These canals provide pathways for blood vessels to reach the osteocytes (bone cells) within the lacunae. The blood vessels deliver oxygen and nutrients necessary for the survival and functioning of the cells within the bone.
2. Nerve supply: Along with blood vessels, these canals also contain nerves that provide sensory and motor innervation to the bone tissue. Nerves play a role in transmitting pain, controlling blood flow, and regulating bone remodeling.
3. Exchange of nutrients and waste products: The canals allow for the exchange of nutrients and waste products between the osteocytes and the surrounding blood vessels. Metabolic waste products generated by the cells can diffuse out of the canals, while necessary nutrients can enter the canals and reach the bone cells.
4. Communication and coordination: The system of canals allows for communication and coordination between different regions of the bone. They facilitate the integration and synchronization of cellular activities within the bone tissue, contributing to its overall structure and function.
