1.	They have two articulations surfaces on their ventral end.
2.	They have two articulations surfaces on their dorsal end.
3.	They have two articulations surfaces on their ventral end and two on the dorsal end.
4.	They have two articulations surfaces on their ventral end and one on the dorsal end.

1. Xiphoid process of the sternum

2. Acromion of the scapula

3. Glenoid cavity of the scapula
