The cartilaginous joints are the joints which allows the movement between the bones. They are of two types that are primary cartilaginous joints and secondary cartilaginous joints.

The primary cartilaginous joints are called as synchondrosis. These joints connect the bones with a hyaline cartilage. These can be found near the ossification centers.

The secondary cartilaginous joints are called as symphysis. These joints connect the bones with hyaline and fibrocartilaginous joints. These are usually found at the midline.
