An articulation in which bones are joined by is called a synchondrosis. Functionally, all synchondroses are and thus are classified as . The in children form synchondroses that bind the epiphyses and diaphysis of long bones. When bones stop growing, replaces the synchondrosis and it no longer exists. Other examples of synchondroses are the synchondrosis found between some cranial bones of the skull and , the articulations between each bony rib and its respective costal cartilage.

1. hyaline cartilage

2. immobile

3. synarthroses

4. epiphyseal plates

5. osseous tissue

6. sphenoid-occipital

7. costochondral joints

Explanation:

Synchondroses is a cartilaginous joint that is attached by hyaline cartilage in the body that can be temporary or permanent. These bones are immobile as the are not freely mobile or movable so classified as the synarthroses.

The great example of such joints is epiphyseal plates. In children epiphyseal platees form Synchondroses that bind the epiphyses and diaphysis of long bones. Osseous tissue occurs and replace synchondrosis once it does not grow further. Two other examples are sphenoid-occipital costochondral joints.

Thus, the correct answers are :

1. hyaline cartilage

2. immobile

3. synarthroses

4. epiphyseal plates

5. osseous tissue

6. sphenoid-occipital

7. costochondral joints
