High resolution view of the E-face of the fractured collecting canal of the contractile vacuole showing its association with microtubular ribbons and with the smooth spongiome. The E-fracture face of ...

High resolution view of quick-freeze deep-etch of the contractile vacuole E-fracture face. This face, like the collecting canal membrane, is porous indicating that many IMPs have been removed from thi...

A high resolution image of a clump of at least seven small clathrin cages that are probably connected to an early endosome (below the fracture plane). The morphology of these cages shows a tighter pac...

A segment of the edge of the axoneme showing the outer axonemal dynein arms that extend from the A-subfiber of a doublet to bind to the B subfiber of the adjacent doublet. TEM taken on 4/21/88 by C. S...

A portion of an isolated cilium exposing two rows of outer dynein arms arising from subfiber A of each doublet. The heavy chains of the dynein complex are linked to the microtubule by stems that can b...

Quick-freeze deep-etch rotary shadowed replica of a parasomal sac from which a clathrin-coated preendosomal vesicle has pinched off. The typical clathrin cage structure is preserved. Fractured trichoc...

A view of the E-face of the fractured collecting canal of the contractile vacuole showing its association with microtubular ribbons and with the smooth spongiome. The E-fracture face of the smooth spo...

Higher resolution of the area that shows the clathrin-coated cage near the peniculus and clathrin coated preendosomal and partially coated preendosomal vesicles. Early endosomes like the preendosomal ...

The P-face of the ciliary membrane at the base of the cilium has 9 triple rows of IMPs in register with the 9 doublets of the internal axoneme. It is thought that these IMPs may be sites of calcium in...

Quick-freeze deep-etch of granulo-fibrillar material at the crests of the ridges. This material is composed of thinner and shorter filaments that, like the striated bands, appear to bind to the membra...
