  2. Osteon - Wikipedia

    en.wikipedia.org/wiki/Osteon

    Each osteon consists of concentric layers, or lamellae, of compact bone tissue that surround a central canal, the Haversian canal. The Haversian canal contains the bone's blood supplies. The boundary of an osteon is the cement line. Each Haversian canal is surrounded by varying number (5-20) of concentrically arranged lamellae of bone matrix.

  3. Haversian canal - Wikipedia

    en.wikipedia.org/wiki/Haversian_canal

    Haversian canals are contained within osteons, which are typically arranged along the long axis of the bone in parallel to the surface. The canals and the surrounding lamellae (8-15) form the functional unit, called a Haversian system, or osteon .

  4. Bone - Wikipedia

    en.wikipedia.org/wiki/Bone

    It facilitates bone's main functions—to support the whole body, to protect organs, to provide levers for movement, and to store and release chemical elements, mainly calcium. It consists of multiple microscopic columns, each called an osteon or Haversian system.

  5. Lacuna (histology) - Wikipedia

    en.wikipedia.org/wiki/Lacuna_(histology)

    Section parallel to the surface from the body of the femur. X 100. a, Haversian canals ; b, lacunae seen from the side; c, others seen from the surface in lamella , which are cut horizontally. Nucleated bone cells and their processes, contained in the bone lacunae and their canaliculi respectively.

  6. Bone canaliculus - Wikipedia

    en.wikipedia.org/wiki/Bone_canaliculus

    Bone canaliculi are microscopic canals between the lacunae of ossified bone.The radiating processes of the osteocytes (called filopodia) project into these canals. These cytoplasmic processes are joined together by gap junctions.

  7. Endosteum - Wikipedia

    en.wikipedia.org/wiki/Endosteum

    The endosteum (pl.: endostea) is a thin vascular membrane of connective tissue that lines the inner surface of the bony tissue that forms the medullary cavity of long bones.

  8. Volkmann's canal - Wikipedia

    en.wikipedia.org/wiki/Volkmann's_canal

    Volkmann's canals, also known as perforating holes or channels, are anatomic arrangements in cortical bones that allow blood vessels to enter the bones from periosteum.They interconnect the Haversian canals (running inside osteons) with each other and the periosteum.

  9. Bone healing - Wikipedia

    en.wikipedia.org/wiki/Bone_healing

    Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
