Primary cartilaginous joints are found in the epiphyses and diaphyses of the long bone of the femur. Secondary cartilaginous joint are connected together by a flattened disc of fibrocartilage of a more or less complex structure. The bones are connected by bands of white fibrous tissue termed ligaments Examples of amphiarthrosis include the intervertebral disks of the spine and the joint between the manubrium and the body of the sternum and the pubic symphysis of the
