  2. Osteocyte - Wikipedia

    en.wikipedia.org/wiki/Osteocyte

    The cell body varies in size from 5–20 micrometers in diameter and contain 40–60 cell processes per cell, [4] with a cell to cell distance between 20–30 micrometers. [3] A mature osteocyte contains a single nucleus that is located toward the vascular side and has one or two nucleoli and a membrane. [ 5 ]

  3. Osteochondroprogenitor cell - Wikipedia

    en.wikipedia.org/wiki/Osteochondroprogenitor_cell

    Osteoblasts are cells that group together to form units, called osteons, to produce bone. Runx2 (which may also be known as Cbfa1), and Osx (a zinc finger containing transcription factor) are necessary for osteochondroprogenitor cells to differentiate into the osteoblast cell lineage.

  4. Osteon - Wikipedia

    en.wikipedia.org/wiki/Osteon

    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. Near the surface of the compact bone, the lamellae are arranged parallel to the surface; these are called circumferential lamellae.

  5. Osteoblast - Wikipedia

    en.wikipedia.org/wiki/Osteoblast

    However, in the process of bone formation, osteoblasts function in groups of connected cells. Individual cells cannot make bone. A group of organized osteoblasts together with the bone made by a unit of cells is usually called the osteon. Osteoblasts are specialized, terminally differentiated products of mesenchymal stem cells. [1]

  6. Bone - Wikipedia

    en.wikipedia.org/wiki/Bone

    A bone is a rigid organ [1] that constitutes part of the skeleton in most vertebrate animals. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility.

  7. Lacuna (histology) - Wikipedia

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

    This constitutes the so-called capsule of the space. Each lacuna is generally occupied by a single cell, but during the division of the cells, it may contain two, four, or eight cells. Lacunae are found between narrow sheets of calcified matrix that are known as lamellae ( / l ə ˈ m ɛ l i / lə- MEL -ee ).

  9. Periosteum - Wikipedia

    en.wikipedia.org/wiki/Periosteum

    The periosteum is a membrane that covers the outer surface of all bones, [1] except at the articular surfaces (i.e. the parts within a joint space) of long bones. (At the joints of long bones the bone's outer surface is lined with "articular cartilage", a type of hyaline cartilage.)
