Introductory Anatomy: Joints This is a radiograph of the knee region. Seen in the radiograph are two important kinds of joint with quite different functions. Between the secondary centres of ossification or epiphyses of the bones and the metaphyses are joints where movement is positively discouraged: between the femur and the tibia is the synovial knee joint proper, where movement is positively encouraged. So where two or more bones come together we find a joint: the range of movement at joints may be zero or a just a little give, or extremely large. Joints are accordingly classified 1. fibrous and cartilaginous joints where two bones are separated by a deformable intermediate 2. synovial joints where one surface slides freely over another. Fibrous joints. We have already mentioned the joint between the bony shaft and cartilage at the ends of long bones. This is a synchondrosis, a cartilage sandwich with bone on either side: bone and cartilage fit together perfectly and the whole thing is cup shaped. If movement occurs the
