Fine structural distinction between ganglia of the outer and inner submucosal plexus in porcine small intestine
Acta Anat (Basel).
1994.
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.
