[Morphofunctional characteristics of nerve fibers of the testicular plexus].
In 25 mongrel dogs, under conditions of complete aseptic, various surgical interventions have been performed with the aim of a systemic denervation of the testicular artery. In 120-168 h the animals are sacrificed under anesthesia. The nerves of the arterial plexus are studied by means of some impregnation techniques. Myelin fibres of large, middle and small diameters, as well as amyelinate conductors are stated to belong to neurocytes of the spinal ganglia. Most of the amyelinate fibres in the testicular nerves are connected with cells of the sympathetic ganglia. In the system of the testicular afferent connections, besides fibres of the spinal origin, there are axons of the peripheral sensitive cells of Dogeal II type which play the role of sensitive elements in the structure of the reflective arc, situating outside the central nervous system, and form synapses with neurocytes of the sympathetic ganglion.
