Transport of pre-SVs in wild type (jsIs821) L4. Transport of GFP::RAB-3 marked pre-SVs along the PLM neuronal process in wild type (jsIs821) L4 C. elegans hermaphrodites. The observed region spans 40μm (x-axis) X 13μm (y-axis). The neuronal process is oriented such that the cell body is to the left and anterograde transport occurs from left to right.
