  2. Osteocyte - Wikipedia

    en.wikipedia.org/wiki/Osteocyte

    They are the most common cell type in bone (31,900 per cubic millimeter in bovine bone to 93,200 per cubic millimeter in rat bone). [6] Most of the receptor activities that play an important role in bone function are present in the mature osteocyte. [6] Osteocytes are an important regulator of bone mass.

  3. Bone - Wikipedia

    en.wikipedia.org/wiki/Bone

    Bone tissue (osseous tissue), which is also called bone in the uncountable sense of that word, is hard tissue, a type of specialised connective tissue. It has a honeycomb-like matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells.

  4. Osteoid - Wikipedia

    en.wikipedia.org/wiki/Osteoid

    Osteoblasts begin the process of forming bone tissue by secreting the osteoid as several specific proteins. The osteoid and its adjacent bone cells have developed into new bone tissue when it becomes mineralized. Osteoid makes up about fifty percent of bone volume and forty percent of bone weight. It is composed of fibers and ground substance.

  5. Endochondral ossification - Wikipedia

    en.wikipedia.org/wiki/Endochondral_ossification

    Endochondral ossification is responsible for development of most bones including long and short bones, [4] the bones of the axial (ribs and vertebrae) and the appendicular skeleton (e.g. upper and lower limbs), [5] the bones of the skull base (including the ethmoid and sphenoid bones) [6] and the medial end of the clavicle. [7]

  6. Hard tissue - Wikipedia

    en.wikipedia.org/wiki/Hard_tissue

    Bone is an active tissue composed of different cells. Osteoblasts are involved in the creation and mineralisation of bone; osteocytes and osteoclasts are involved in the reabsorption of bone tissue. The mineralised matrix of bone tissue has an organic component mainly of collagen and an inorganic component of bone mineral made up of various salts.

  7. Anatomical terms of bone - Wikipedia

    en.wikipedia.org/wiki/Anatomical_terms_of_bone

    A sesamoid bone is a small, round bone that, as the name suggests, is shaped like a sesame seed. These bones form in tendons (the sheaths of tissue that connect bones to muscles) where a great deal of pressure is generated in a joint. The sesamoid bones protect tendons by helping them overcome compressive forces.

  8. Intramembranous ossification - Wikipedia

    en.wikipedia.org/wiki/Intramembranous_ossification

    The following bones develop in humans via Intramembranous ossification: [3] Flat bones of the face; Most of the bones of the skull; Clavicles; Other bone that formed by intramembranous ossification are: cortices of tubular and flat bones as well as the calvaria, upper facial bones, tympanic temporal bone, vomer, and medial pterygoid process.

  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.)
