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...

High resolution quick-freeze deep-etch image of a fracture through the radial canal of the contractile vacuole. This technique presents a picture of a confusing array of non-etchable material surround...

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...

Quick-freeze deep-etch of an ampulla. The P-fracture face has numerous IMPs. The microtubular ribbon now forms two bands next to this ampulla. The ribbons will split into additional bands as they pass...

A circular depression on the dorsal surface of the cell marks the expulsion site of a contractile vacuole. This is referred to as the contractile vacuole “pore.". Microtubules encircle the pore. Tr...

High resolution image of two parasomal sacs that are oriented perpendicular to the basal bodies. The top parasomal sac has a clathrin cage around it's coated pit area. The P-face of the plasma membran...

A transverse section of the cortex of Conchophthirus curtus reveals details of cortical structure. This includes the nature of the cell membrane and the alveolar membranes that reside immediately belo...

Vestibular kinities and the cortical architecture adjacent to the oral apparatus of Conchophthirus curtus. The negative magnification is 15,500X. The raw film was scanned with an Epson Perfection V750...

Image of the pellicle of Opercularia coarctata. Indentations of the plasma membrane penetrate the alveolar membranes end as coated pits. These pits are also known as pellicular pores are homologous to...
