Bundles of microtubules (arrowheads) arise from along the
elaborately woven blanket of the filamentous reticulum (fr)
that covers the ribbed wall of the right side of the buccal cavity. A
bundle forms beneath the bottom of each rib of the ribbed wall
(rw) and runs parallel to the depression of the rib. These
bundles then extend beyond the posterior terminus of the buccal cavity
where they are then collectively called the postoral fiber. In
addition single microtubules (mt) seem to lie deeper in the
cytosol at approximately right angles to the bundles. mac,
macronucleus. EM taken on 7/5/96 by R. Allen with Zeiss 10A TEM. Neg.
