[Preparation of the spinal neurons and their bushy receptors for morphophysiological study].
A preparation of the sensory neuron of the spinal ganglion with dendritic processes for simultaneous morphological and physiological investigations is described. It consists of a frog urinary bladder with bushy interoceptors in its wall, two vesicle neurons, two abdominal branches of the X spinal nerves and two IX spinal ganglia with ventral and dorsal roots branching off from them. The total length from the receptors to the ganglion neurons is 20-30 mm. In the ganglia a zone of the neuronal bodies localization is found, their processes form receptors; the zone includes as many as 9 neurons, 50-80 mkm in size. A vital fine structure of the ganglion cells and their satellites is traced. There are three types of cells in the ganglion--large, middle and small. Electrophysiological control has demonstrated that the preparation is viable for several hours.
