Table 2.
Average angles and directional distances of observed canal pathways. The table below summarizes the average angle and distance traveled in each component when a canal traveled of the vertical in each of the major canal pathways in both planes. The straight inferior trend viewed in the coronal plane is not included because canals following this pathway followed a direct vertical path.
