And the osteon consists predominantly of this matrix, the extracellular matrix that is created by osteoblast. And once we create this matrix, the osteoblasts basically differentiate into our osteocides shown by these purple regions. These osteocides basically have these extensions known as processes. 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.
