Corbiculacean Gill Morphology - The Mucous Cells
The mucous cell of the gill filament
of Corbicula fluminea is situated between the eu-latero-frontal
cell and the lateral cells. As the
name suggest, this cell secretes mucous. Whether this mucous is
an integeral part of the particle capture mechanism during feeding
is not certain.
Below are images of mucous cells.
A TEM of a mucous cell of Corbicula fluminea. To the
right are the cilia coming from lateral cells. You may be able
to see the convoluted ER and secretory apparati that fill the
interior of this cell.

a Eu-lateral-frontal cell toward the top and a lateral cell toward
the bottom of the image. Visible is a mucous strand eminating
from the cell. To the left are the lateral cilia in oblique section.
