Abstract
Ultrastructural differences between ganglia of the plexus submucosus internus (Meissner; PSI) and plexus submucosus externus (Schabadasch; PSE) are described. Comparison revealed a different glia index (ratio glia per neuron) between the PSE (3:1) and the PSI (1:1), the arrangement of PSI neurons in compartments and the appearance of broad membrane-to-membrane appositions inside the compartments of the PSI. Structural and immunohistochemical differences between the two plexuses are discussed. In general, PSE neurons show a wider variety in size and shape than most of the PSI neurons.Keywords
