What are the different synchondroses?

Sychondoses are immovable, temporary joints that connect two bones with cartilage. In adulthood, the body converts cartilage into bones by a process known as ossification or transforms it into fibrocartilage. In humans, these joints are found in the skull, connect long bones such as the tibia and femur's legs, and attach the first rib to the breast.

Anatomists classify joints such as fibrous, cartilage or synovial. The joints of synchondrosis are cartilage and initially, the type of cartilage known as Hyaline combines both bones. Hyalin cartilage contains less collagen than denser fibrocartilage that can replace it. As soon as fibrocartilage replaces the hyaline cartilage, the joints are no longer referred to as synchondroses, but instead they are called Symphysses. If the cartilage undergoes the ossification, the joint disappears into the bone and loses its independent identity.

Synchondroses in the skull of Osify to form bone tissue. The first is to join them are usually ossified by the first birthday of the child. OtherSynchondroses take from 2 to 14 years to turn into a bone, although rarely one or more synchondrosis can remain until early adulthood. Synchondroses skulls are often associated with the release of the child's passing through the birth of the channel, but also allow the infant's brain to grow rapidly.

in the leg, the end of the femur and the end of the tibia is not fused at birth. Both ends actually have synchondrosisis that separates them. This impossible joint is what allows the bone to continue to grow with the child. At about the age of 25, synchondrosis ossified and the joint disappears into the bone.

Unlike synchondros found in the skull and legs, the joint attaches the rib to the pectoral bone, more on fibrocartilage than to the bone. This is a fibrous cartilage is harder than Hyaline and allows even less movement. Fibrocartilage acts to stabilize the upper chest, a chest area containing lungs and hearts.

cartilage joints such as synchondroses have little similarity to synovial joints, but share some of the same properties as fibrous joints. Synovial joints have a large range of movement and the classification includes joints such as knees, shoulders and elbows. Fiber joints have a small ability to move and some of them disappear with age, as well as synchondoses. However, unlike synchondosis, the fibrous joint has bonds that help maintain the connection between the bones.
