Morphological Features of Dogel’s First Type Neurons In the Ganglia of Gallbladder Wall

Abstrak

The common bile duct contains a large number of nerve elements, it contains the largest ganglia with many neurons. Among the neurons of these ganglia, it is difficult to differentiate Type I Dogel cells. The aim of the study was to identify some morphological features for the identification of Dogel type I nerve cells in the intramural ganglia of the common bile duct in dogs. Neurohistological impregnation research methods were applied. It has been established that around the bodies of nerve cells of type I Dogel there is always a clear space free from nerve fibers and often even from gliocytes. A feature of Type I Dogel cells is also the intense perception of silver nitrate during impregnation (hyperimpregnation) in comparison with other neurons of the node.
