[The ultrastructure of the central nervous system neurons and synapses in the edible snail under a high concentration of potassium ions].
The morphometric and electron microscopic results on neuronal and synaptic ultrastructure of central nervous system of Helix pomatia snail, incubated in vitro in media with high potassium ion concentration are represented in the present paper. The activation of glial cells is revealed with its close attachment to neurons. The energization of neuronal mitochondria and signs of cytoplasmatic oedema are clearly visible. The penetration of glial endings in the large neuronal branches and the synaptic vesicles confluence in neuronal endings are found.
