Fig. 14: one radial arm

This micrograph shows a filled ampulla of a radial arm (#10 of CVC in Figures 5 to 9) connected to its collecting canal. Most of the surrounding smooth spongiome has been incorporated into the expanded ampulla as well as the collecting canal although excess smooth spongiome (ss) still remains around the collecting canal. In addition decorated spongiome (ds) appears, but only around the collecting canal as it is always absent from the vicinity of the ampulla. (Section #66 from same series as Figures 5 to 9). EM taken on 4/15/80 by R. Allen with Hitachi HU11A TEM. Neg. 7,000X. Bar = 1µm. Published in J. Protozool. 35:63-71, 1988.
