Two parasomal sacs (ps) that are oriented perpendicular to the
basal bodies (bb). The top parasomal sac has a clathrin cage
(arrow) around its coated pit area. The P-face of the plasma
membrane (Ppm) has some IMPs, particularly around
the neck of the basal body. Alveoli (al) contain some
non-etchable material. Striated bands (sb) are anchored to the
cytosolic face of the inner alveolar membrane to which an
inconspicuous epiplasm (ep) is bound. Fractured kinetodesmal
fibers (kd) show evidence of longitudinally ordered packing of
subunits even though cross striations are more prominent in thin
sections. EM taken on 6/4/91 by R. Allen with Zeiss 10A TEM. Neg.
24,800X. Bar = 0.2µm.
