| Start |   |   | Starting point of the interactions represented in the diagram. See Starts (OOM). | 
| Interaction activity |   |   | Reference to a sequence diagram, communication diagram, or interaction overview diagram. See Interaction References and Interaction Activities (OOM). | 
| Flow |   |   | Flow of control between two interactions. See Flows (OOM). | 
| Decision |   |   | Decision the flow has to take when several paths are possible. See Decisions (OOM). | 
| Synchronization |   |   | Enables the splitting or synchronization of control between two or more flows. See Synchronizations (OOM). |
