Document Summary
Articulations are the junctions between 2 bones. Synathrodial articulations are between 2 joints that are considered immovable but they will move a tiny bit to absorb force if necessary: sutures in the skull are a good example of this. Amphiarthrodial articulations are slightly movable because of a fibrocartilagenous disc, ligament or membrane that links the 2 bones. These joints have give so they provide shock absorption. A good example is the intervertebral discs of the spine: main function is to maintain stability. Diarthrodial articulations are joints that can move freely. They are the most common and there are several types of diarthrodial articulations: a good example is the knees and hips and elbows, these joints allow the most forceful movements and have the greatest range of motion. The knee has 6 degrees of freedom because it has 2 things coming together and there are.
