Morphological evidence for double innervation of neurons of peripheral ganglia

  • V. I. Pilipenko
Morphology and Pathomorphology


In experiments on cats synaptic connections of the effector neurons in the peripheral ganglia of the abdominal and pelvic organs and heart were studied by the methods of experimental neuromorphology. Experimental evidence obtained confirm the data presented in the previously published works on the synaptic connections of the effector neurons with the axons of the peripheral sensory neurons. The preganglionic fibers terminate with the typical end-loops of free terminal fibers. The synaptic connection between the peripheral sensory neurons is effected at the expense of the terminal fibers distributed in the intercellular network, and entering into an intimate association with the dendrites and the cellular bodies. Double synaptic connection is found in the majority of the neurons. The morphological pictures point to an uneven innervation of the individual neurons by the preganglionic fibers and axons of the peripheral sensory neurons. Physiological investigations respective convergence of nerve impul ses on individual neurons give an approach to the understanding of the mechanism governing the CNS subordinating influences on the peripheral reflexes mechanisms.
