Quantitative electron microscopic study of the innervation of different types of specialized sinus node conducting myocytes and of working myocytes in the perinodal myocardium of the right atrium was carried out in intact dogs. Differences were found in diameters of unmyelinated nervous fibers and their efferent terminals and distances between them and sarcolemmas of myocytes of the types studied. It was demonstrated that qualitatively different synaptic vesicles in the efferent terminals near the nodal and working myocytes are encountered with different frequency. Similar parameters of innervation of the nodal and working myocytes in sinauricular region of the heart were compared in intact dog and rat.
在完整的犬类动物身上，对右心房窦房结周围心肌中不同类型的特殊窦房结传导性心肌细胞和工作心肌细胞的神经支配进行了定量电子显微镜研究。研究发现，在所研究的不同类型心肌细胞中，无髓神经纤维及其传出终末的直径、它们与肌细胞膜之间的距离存在差异。结果表明，在结区和工作心肌细胞附近的传出终末中，定性不同的突触小泡出现的频率不同。对完整犬类动物和大鼠心脏窦房区域的结区和工作心肌细胞的神经支配的类似参数进行了比较。
