The type of joint formed from cartilage covering the articular surfaces of bones is called a synovial joint. In these joints, the cartilage provides a smooth, lubricated surface for articulation, allowing for a wide range of motion. Synovial joints also have a synovial membrane that produces synovial fluid, further facilitating movement and reducing friction. Examples include the knee, elbow, and shoulder joints.
The articular cartilage is the thin layer of white tissue covering the bone in the joint space. The articular cartilage is made of hyaline cartilage.
Articular (AKA Hyaline) cartilage is formed from condensed mesenchyme tissue, which differentiates into chrondrocytes and begins secreting extracellular matrix.
Articular cartilage arises from the mesenchyme layer of the developing embryonic limb bud. Mesenchymal cells differentiate into chondrocytes, which then form the specialized extracellular matrix that makes up articular cartilage. This process occurs during early stages of skeletal development.
A bone collar is formed around the hyaline cartilage model. The hyaline cartilage is then caviated within the cartilage model. Next, the periosteal bud is invaded with internal cavities and spongy bone is formed. This is followed by the formation of the medllary cavity as ossification continues. The epihyses are ossificated and when this process is completed, the hyaline cartilage remains only in the epiphyseal plates and articular cartilages.
In fully formed, non-growing bones, cartilage is found on the ends of bones where they articulate with other bones.

The femur is formed through the endochondral ossification process. This is where bone replaces the cartilage. There are six steps in this type of ossification and they are as follows; one the development of cartilage model, two the growth of the cartilage model, three the development of the primary ossification center, four the development of the medullary cavity, five the development of the secondary ossification centers, and six the formation of articular cartilage and the epiphyseal plate.
No, membrane bones do not develop from hyaline cartilage structures. Membrane bones are formed directly from mesenchyme tissue through intramembranous ossification, while hyaline cartilage serves as a precursor for endochondral ossification, where bones are formed by replacing cartilage with bone tissue.
Yes, it is true that in a developing fetus, the long bones are initially formed from hyaline cartilage. This cartilage serves as a scaffold that is gradually converted into bone through a process known as endochondral ossification.
is the most widespread type of cartilage, which has abundant collagen fibers hidden by a tubbery matrix with a glassy, blue-white appearance.
The process in which mineral matter replaces previously formed cartilage is called ossification or calcification. This process involves the deposition of calcium salts and other minerals to harden the cartilage into bone tissue.
