What is the definition of Endochondral?
Definition of endochondral : relating to, formed by, or being ossification that takes place from centers arising in cartilage and involves deposition of lime salts in the cartilage matrix followed by secondary absorption and replacement by true bony tissue.
Is Endochondral an ossification?
Endochondral ossification is the process by which the embryonic cartilaginous model of most bones contributes to longitudinal growth and is gradually replaced by bone.
Where are Endochondral bones found?
Endochondral ossification is the process of bone formation in which cartilage scaffolds, arranged in zones, are gradually replaced by bone. It occurs at the articular/epiphyseal and metaphyseal growth plates and at secondary centers of ossification, such as the carpal and tarsal bones.
Are ribs endochondral?
The vertebrae, ribs, and sternum all develop via the process of endochondral ossification.
Which bones are endochondral?
Endochondral ossification is the process of bone development from hyaline cartilage. All of the bones of the body, except for the flat bones of the skull, mandible, and clavicles, are formed through endochondral ossification.
Is the femur endochondral?
Endochondral ossification is the process by which bone tissue is formed in early fetal development. It begins when MSCs start to produce a cartilage template of long bones, such as the femur and the tibia, upon which bone morphogenesis occurs.
What are Osteoids?
Osteoblasts work in teams to build bone. They produce new bone called “osteoid” which is made of bone collagen and other protein. Then they control calcium and mineral deposition. They are found on the surface of the new bone.
What is an example of an endochondral bone?
All of the bones of the body, except for the flat bones of the skull, mandible, and clavicles, are formed through endochondral ossification. In long bones, chondrocytes form a template of the hyaline cartilage diaphysis.
How is Endochondral bone formed?
In endochondral ossification, bone develops by replacing hyaline cartilage. Cartilage does not become bone. Instead, cartilage serves as a template to be completely replaced by new bone. Endochondral ossification takes much longer than intramembranous ossification.
Where does Endochondral lengthening occur?
Both endochondral and perichondral bone growth both take place toward epiphyses and joints. In the bone lengthening process during endochondral ossification depends on the growth of epiphyseal cartilage. When the epiphyseal line has been closed, the bone will not increase in length.
