| In the nonsynovial type, known also as synarthrosis, the skeletal parts are connected by nonosseous material that permits bending or twisting. |
| An example of a synarthrosis is the suture in the skull between skull bones. |
| There are two basic structural types of joint: diarthrosis, in which fluid is present, and synarthrosis, in which there is no fluid. |
| Two adjacent ribs, often five and six, and six and seven, sometimes articulate at their costal cartilages by a diarthrosis, synarthrosis, or syndesmosis. |
