Abstract
The effect of glycerol on the gap junctions found in a number of tissues from several invertebrate phyla was studied. Glycerol affected both the spatial arrangement of the particles within the membranes and their fracturing properties in unfixed tissues. This effect of glycerol may be of diagnostic use in enabling the junctions to be separated into a number, or spectrum of types. This study has extended the knowledge of B-type gap junction occurrence from only Arthropoda to Coelenterata, Platyhelminthes and Annelida. B-type gap junctions appear to have a 12-nm particle separation in contrast to the 10-nm separation of the A type.
