  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. Bone marrow - Wikipedia

    en.wikipedia.org/wiki/Bone_marrow

    The bone marrow produces the cellular elements of the blood, including platelets, red blood cells and white blood cells. While much information can be gleaned by testing the blood itself (drawn from a vein by phlebotomy ), it is sometimes necessary to examine the source of the blood cells in the bone marrow to obtain more information on ...

  4. Osteonectin - Wikipedia

    en.wikipedia.org/wiki/Osteonectin

    Osteonectin is an acidic extracellular matrix glycoprotein that plays a vital role in bone mineralization, cell-matrix interactions, and collagen binding. Osteonectin also increases the production and activity of matrix metalloproteinases , a function important to invading cancer cells within bone.

  5. Ossification - Wikipedia

    en.wikipedia.org/wiki/Ossification

    These blood vessels will eventually develop into red bone marrow. Mesenchymal cells on the bone surface form a membrane known as the periosteum. Osteoblasts secrete osteoid in parallel with the existing matrix, creating layers of compact (cortical) bone.

  6. Bone - Wikipedia

    en.wikipedia.org/wiki/Bone

    Within these spaces are bone marrow and hematopoietic stem cells that give rise to platelets, red blood cells and white blood cells. [16] Trabecular marrow is composed of a network of rod- and plate-like elements that make the overall organ lighter and allow room for blood vessels and marrow.

  7. Osteoblast - Wikipedia

    en.wikipedia.org/wiki/Osteoblast

    In the hollow within bones are many other cell types of the bone marrow. Components that are essential for osteoblast bone formation include mesenchymal stem cells (osteoblast precursor) and blood vessels that supply oxygen and nutrients for bone formation. Bone is a highly vascular tissue, and active formation of blood vessel cells, also from ...

  8. Matrix (biology) - Wikipedia

    en.wikipedia.org/wiki/Matrix_(biology)

    Bone is a form of connective tissue found in the body, composed largely of hardened hydroxyapatite-containing collagen.In larger mammals, it is arranged in osteon regions. . Bone matrix allows mineral salts such as calcium to be stored and provides protection for internal organs and support for locomoti

  9. Bone resorption - Wikipedia

    en.wikipedia.org/wiki/Bone_resorption

    Bone tissue is a dynamic system with active metabolism. [24] Bone tissue remodelling or bone remodeling is a successive chain of old bone matrix removal and its replacement with a new one. [25] These processes make a child’s skeleton grow and extend, while childhood is characterized by bone tissue growth rather than its resorption.
