Another example of an amphiarthrosis is the pubic symphysis of the pelvis. This is a cartilaginous joint in which the pubic regions of the right and left hip bones are strongly anchored to each other by fibrocartilage. This joint normally has very little mobility.
There are two types of amphora: the neck amphora, in which the neck meets the body at a sharp angle; and the one-piece amphora, in which the neck and body form a continuous curve. The first is common from the Geometric period (c. 900 bc) to the decline of Greek pottery; the second appeared in the 7th century bc. The height of amphorae varies from large Geometric vases of 5 feet (1.5 metres) to examples of 12 inches (30 centimetres) or even smaller (the smallest are called amphoriskoi).
