Abstract

Authors investigated the cyto-topographic construction of ganglia of Anodonta cygnea by the impregnation technique. It was established that the large cells are present primarily in the immediate neighbourhood of the nerves, that originate from the ganglia and that their thick (2—3 µ) axons may be followed up until the initial section of the branches of nerves. In the cortex there are areas which contain only medium-sized or small nerve cells and are in contact only with thin axons. In the posterior part of the visceral ganglion groups of motor-like cells are observable, which are separated from the cortex and may be taken for nucleus posterior. In the visceral ganglia unilateral and transversal pathways are also observable.
