  • Abstract
  • Look Inside

Differentiation of sympathetic nervous ti-ssues especially truncus sympathicus of 19 embryoes and fetuses (I-VIII month), 28 non-chromaf fin sympathetic tumors (15 neuro-blastomas, 4 ganglioneuroblastomas, 9 gangli-oneuromas) and a peculiar ganglioneuroma, to which the author conveniently refered as "ganglion-cell-formative neurinoma" are stu-died histologically.

I Embryonal sympathetic nervous tissues

a) The degree of the development of gan-glion conspicuously varies from fetus to fe-tus of even the same month, and also from ganglion to ganglion of a same fetus. This holds true with the individual nerve cell in a ganglion, too. Differentiation of neuro-blasts in the adrenal medulla comes last.

b) Neuroblast begins to produce 1 or 2 or several fibrillar processes, and then develops into a multipolar form. Fibrillar processes first stretch to confluent into fine networks, then into either of the shapes of grape veins, complicated branches, and spokes (fibrils of a rosette), which gather together into the form of pampas grass and finally a large river (bundles of embryonal non-medullated nerve fibres without neurolemma).
