title: [Ultrastructure of the dendrites of neurons of the brain stem reticular formation in acute hypoxic hypoxia].
abstract: In 45 adult rats (Wistar strain) neuronal dendrites of the reticular formation were studied electron microscopically at an acute hypoxic hypoxia. Structural changes in neurons of the reticular formation, were demonstrated to begin, as a rule, in the terminal portions of the dendrites. Dystrophic and destructive changes in dendrites are always more pronounced than in the pericaryon and are not infrequently they terminate in destruction of cytoplasmic islets. Submicroscopic changes in the dendrites are classified according to the dynamics of their development. Taking into consideration a specific role of the neuronal dendrites of the reticular formation under certain physiological conditions, it is possible to conclude that dendritic damage is of major importance in functional disturbance of the reticular formation at hypoxic hypoxia.
