In a high frequency electric field, two flashing areas were observed during each contraction of the heart in the vagosympathetic trunk of a paralyzed frog with an intact brain. One area with a higher diameter was moving along the nerve from the heart at a speed of 16.6 ± 0.2 m/s. It was identified as afferent. Another area with a smaller diameter was spreading along the nerve towards the venous sinus of the frog heart at a speed of 5.6 ± 0.3 m/s, and it was efferent. 相似文献

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. 相似文献
