title: [Ultrastructure of the caudal mesenteric ganglion neurons during early development in kittens].
abstract: Electron microscopy was used to study the peculiarities of the development of nervous elements in the sympathetic caudal mesenteric ganglion (CMG) in the cat from the moment of birth until the end of the second month of life. The discordance in the rate of maturation of both neurons and their endings was observed. In newborn kittens, mature neurons, glial cells and synapses were observed together with many immature ones. In 14-day-old animals, the proportion of immature neurons decreased, while destruction of neurons was observed more frequently in this age. In CMG of the animals of all the age groups, axodendritic synapses were found most frequently and axosomatic synapses were observed more rarely. Finally, the ultrastructure of CMG in kittens become comparable to that of adult animals at the age of 60 days.
