Light and electron microscopic features of the human ascending aortic fold are described. Histological examination showed the characteristic epicardial structures continuous with a stroma of abundant adipose tissue. In addition, randomly distributed tissue resembling the carotid body was observed by both light and electron microscopy throughout postnatal life, from a fullterm stillborn fetus to the oldest subject (65 y). The size of the paraganglionic cell nests was variable at all ages. The presence of paraganglia in the aortic fold raises the possibility that they are concerned with chemoreception.
本文描述了人类升主动脉皱襞的光镜和电镜特征。组织学检查显示，特征性的心外膜结构与富含脂肪组织的基质相连。此外，从足月死产胎儿到最年长者（65岁），在整个出生后的生命过程中，通过光镜和电镜均观察到类似颈动脉体的随机分布组织。神经节旁细胞巢的大小在所有年龄段均有所不同。主动脉皱襞中副神经节的存在增加了它们与化学感受有关的可能性。
