Histochemical, electron-microscopic, pharmacological and physiological studies of structural and functional features of the frog blood vessels revealed a difference in the peripheral neural apparata of different vessels as expressed by different grades of the contractile responses to exogenous substances and electrical stimulation: the better innervated a vessel the better response is mediated by the alpha-adrenoreceptors. The beta-adrenoreceptors have only been found in innervated vessels. The data obtained suggest that vessels of amphibia are in general similar to vessels of vertebrates but the species specifics associated with behaviour and environment of animals determine a number of specific features in structural-functional organization of vessels. The diversity of structure and functioning of blood vessels found in amphibia attests a differentiation of mechanisms of vessel regulation in different areas of the vascular bed.
对青蛙血管的结构和功能特征进行的组织化学、电子显微镜、药理学和生理学研究表明，不同血管的外周神经装置存在差异，这表现为对外源性物质和电刺激的收缩反应程度不同：血管的神经支配越好，α-肾上腺素能受体介导的反应就越好。β-肾上腺素能受体仅在有神经支配的血管中被发现。所获得的数据表明，两栖动物的血管总体上与脊椎动物的血管相似，但与动物行为和环境相关的物种特异性决定了血管结构-功能组织中的一些特定特征。两栖动物血管结构和功能的多样性证明了血管床不同区域血管调节机制的分化。
