title: Study of the celiac ganglia development.
abstract: The celiac ganglia and the visceral plexus are complexes structures, disposed in the proximity of the main collateral branches of the aorta. Pre visceral ganglia are sympathetic ganglia chains between the lateral vertebral sympathetic chain and viscera. Our study is made in the anatomy lab on 30 adult human bodies, one of new born and 10 human fetal specimens with crown-rump lengths from 9 to 28 cm. It was used the argental impregnation by Bielschowsky on block and Trichrome Masson methods for microscopic evidence. Prenatal, celiac ganglia are not a good defined morphological unit. They show a delay of neuroblastic maturation, comparing with the par vertebral ganglia. The nervous functional unit is represented by the neuron. The ontogenesis of the celiac ganglia follows several stages. Then, the neuronal specialization and the functional neuronal maturation are processes based on the numeric and morphological remodeling of the neuronal connecting figure, pre ganglia and post ganglia.
