This group represents a serial series of sections. At the level of this section, a little deeper in the cell the spongiome of the CV is more pronounced. Oral membranelles in the buccal cavity are indicated by three ciliary rows per membranelle. One of several membranelles making up the perioral ciliature forms a tuft at the top. The cell’s pellicle consists of a plasma membrane and alveolar sac system. TEM taken on 3/12/71 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 3,800X. Bar = 2µm. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared thicker to accommodate the series.
