title: [Receptors with circular nerve apparatus].
abstract: The observations conducted by Bielschowski-Gross method and intravital staining with methylene blue after A.S. Dogiel have shown that the receptors with an annular nervous apparatus are located in the muscular sheath, nerve bundles and ganglia of the intermusclar plexus of the oesophagus, stomach and small intertine of birds. For the first time it was shown taht the receptors with the annular nervous apparatus were not of the central origin  but might be formed by dendrites of the vegetative neurons of digestive tract.
