  2. Endoplasmic reticulum - Wikipedia

    en.wikipedia.org/wiki/Endoplasmic_reticulum

    Different types of cells contain different ratios of the two types of ER depending on the activities of the cell. RER is found mainly toward the nucleus of the cell and SER towards the cell membrane or plasma membrane of cell. The outer face of the RER is studded with ribosomes that are the sites of protein synthesis.

  3. 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 ...

  5. Ossification - Wikipedia

    en.wikipedia.org/wiki/Ossification

    Diagram showing stages of endochondral ossification. Endochondral ossification is the formation of long bones and other bones. This requires a hyaline cartilage precursor. There are two centers of ossification for endochondral ossification. The primary center. In long bones, bone tissue first appears in the diaphysis (middle of shaft).

  6. Bone remodeling - Wikipedia

    en.wikipedia.org/wiki/Bone_remodeling

    Bone tissue is removed by osteoclasts, and then new bone tissue is formed by osteoblasts. Both processes utilize cytokine (TGF-β, IGF) signalling.In osteology, bone remodeling or bone metabolism is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation).

  8. 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.
