## Abstract The embryology of the branchial (pharyngeal) region is reviewed in terms of the embryonic pharynx, branchial apparatus and derivatives, tongue, larynx, and trachea. Derivatives of the branchial pouches, grooves (clefts), and arches are analyzed in relation to each other and to the first

In the central nervous system (CNS), oligodendrocytes have long been considered to be the last cell type to be generated during development. In rodents, the progenitor cells that give rise to oligodendrocytes have been reported to originate in the subventricular zone. Here, we review recent data dem
## Abstract We have recently described large, unipolar neurons (named __bullwhip cells__) that regulate the proliferation of progenitors in the circumferential marginal zone (CMZ) of the postnatal chicken retina (Fischer et al. [2005] J. Neurosci. 25:10157โ10166; [2006] J. Comp. Neurol. 496:479โ494
It has been demonstrated that the spinal cord oligodendrocytes in the vertebrates arise in the ventral ventricular zone adjacent to the floor plate in their early development. Because of the similarities of basic structures in the spinal cord and metencephalon, it is probable that the mode of early
