5[per thousands], 21[per thousands], or 28[per thousands]) were evaluated morphometrically using as criteria the alterations induced in the thickness (in micrometers) of the intralamellar septal cells and the pillar cell flanges; and the height (in micrometers) and numerical density (as microvilli/micrometer of apical membrane) of the apical microvilli on the pillar cells.
To measure the thickness of the septal cells, the test system was placed perpendicularly to the plane of the gill cuticle; valid transects were represented by single planes in which the line segments intersected both cell margins.
olfersii, illustrates the organization of the gill tissue into a semiregular latticework of pillar and septal cells within the lamella.
