And these processes connect to one another via these canals known as our canaliculi. And these canaliculi basically connect and allow adjacent osteocides to exchange important types of materials, important types of nutrients. Now, within our center region of the osteon, we have our harvestion canal which contains our blood vessels, lymph vessels, as well as our nerve cells, our neurons. Now, these concentric regions of matrix is known as our Lamelli. And the space is where we have the osteocides that is known as Lacuni. Now, inside the matrix, we have collagen as the main organic matter and we have the hydroxy appetite as the main inorganic matter.
