SYNOPSISKeurones from the thoracic and abdominal ganglia of the prawn, Leunder aerratw, were studied by optical and electron microscopy.
3.The "trophospongium", which is shown to consist of branching invaginations of the cell membrane, containing processes from the glial cells. It ramifies in the form of long, thin, branching filaments throughout the cytoplasm. Some workers with the light microscope have mistaken these branching invaginations for mitochondria.Long, filamentous mitochondria which might be expected to give the appearance of the "trophospongium" have not been encountered.The following cytoplasmic inclusions have been studied :Parallel lamella associated with granules have rarely been encountered.
2.The "dictyosomes", which are composed of stacks of paired non-granular membranes.
4.The mitochondria, which are mostly short.
