title: [Organogenesis of cranial ganglia in the chick embryo: a comparison of the development of blood vessels and neurocytodifferentiation].
abstract: Neurohistogenetic and vasculogenetic processes have been analytically compared in several cranial ganglia, ciliary (III nerve), semilunar (V nerve), vestibulocochlear (VIII nerve), petrosal (IX nerve) and nodose (X nerve), of chicken embryos from the 3rd to the 12th incubation day. The results indicate that during the organogenesis of these ganglia the formation of the first intrinsic vessels and the successive development of vascular networks follow the beginning and, respectively, the main steps of the neuroblast morphological maturation. The differences noticed by the Authors as concerns the chronological sequence showed by the vasculogenetic events in the various ganglia have been ascribed to the different proceeding of the neurohistogenesis since blood vessels first appear and build networks where the ganglionic development and differentiation are more precocious.
