| Haversian structures acquired characteristic typical to young bones. |
| Every part of a Haversian system is supplied with nutrient fluids derived from the vessels in the Haversian canal and distributed through the canaliculi and lacunae. |
| Such an osteoclastic activity occurs in Haversian channels of cortical bone and subperiostal and endosteal surfaces. |
| In the rare case of a biopsied bone island, the histology has shown compact lamellar bone with prominent Haversian canals. |
| Each Haversian canal is oriented along the long axis of the bone and contains blood vessels and nerves. |
| The compact bone around it and in the diaphysis is formed by a series of Haversian systems. |
