The epithelial bridge is so thin that it is possible to see structures on the other side of the plate in the video clip. ep, epithelial plate; bc, blood capillary. B. Side view of an epithelial bridge showing the two epithelial plates. For this view the capillaries were removed by the operator using appropriate software. epi pl, epithelial plate.
