[Structure and origin of axonal terminals innervating neurons of the vestibular ganglia].
Structural organization of the frog axonal terminals, realizing the synaptic contact with neurons of the vestibular ganglion have been studied electron microscopically. Two kinds of axonal terminals are revealed. They differ in quantitative and qualitative composition of their synaptic vesicles convergated simultaneously in various combinations to the ganglious neurons. Using the axonal retrograde transport of horseradish peroxidase, the nature of these axonal terminals is analysed. Their source is demonstrated to be neurons of the reticular formation and ventral vestibular nucleus of the medulla oblongata, as well as Purkinje's cells of the cerebellum.
