  2. 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.

  3. Bone healing - Wikipedia

    en.wikipedia.org/wiki/Bone_healing

    Intramembranous ossification, mediated by the periosteal layer of bone, occurs with the formation of callus. For endochondral ossification, deposition of bone only occurs after the mineralised cartilage. [citation needed] This process of healing occurs when the fracture is treated conservatively using orthopaedic cast or immobilisation ...

  4. Bone - Wikipedia

    en.wikipedia.org/wiki/Bone

    Endochondral ossification Light micrograph of a section through a juvenile knee joint (rat) showing the cartilagineous growth plates. The formation of bone is called ossification. During the fetal stage of development this occurs by two processes: intramembranous ossification and endochondral ossification. [42]

  5. Fontanelle - Wikipedia

    en.wikipedia.org/wiki/Fontanelle

    The posterior fontanelles ossify within 6–8 weeks after birth. This is called intramembranous ossification. The mesenchymal connective tissue turns into bone tissue. Anterior fontanelle is a diamond-shaped membrane-filled space located between the two frontal and two parietal bones of the developing fetal skull. It persists until ...

  6. 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).

  7. Dermal bone - Wikipedia

    en.wikipedia.org/wiki/Dermal_bone

    A dermal bone or investing bone or membrane bone is a bony structure derived from intramembranous ossification forming components of the vertebrate skeleton, including much of the skull, jaws, gill covers, shoulder girdle, fin rays (lepidotrichia), and the shells of turtles and armadillos.

  8. Development of joints - Wikipedia

    en.wikipedia.org/wiki/Development_of_joints

    The bones that form the base and facial regions of the skull develop through the process of endochondral ossification. In this process, mesenchyme accumulates and differentiates into hyaline cartilage, which forms a model of the future bone. The hyaline cartilage model is then gradually, over a period of many years, displaced by bone.

  9. Skull - Wikipedia

    en.wikipedia.org/wiki/Skull

    The skull is a complex structure; its bones are formed both by intramembranous and endochondral ossification. The skull roof bones, comprising the bones of the facial skeleton and the sides and roof of the neurocranium, are dermal bones formed by intramembranous ossification, though the temporal bones are formed by endochondral ossification.
