用Karnovsky-Root法，观察到胎儿同食管角的肌间丛、粘膜下丛、上皮下丛内有丰富的AchE阳性神经，在肌间丛和肌内神经纤维尤为密集，着色深。粘膜下层内的血管和腺体周围、粘膜肌内神经纤维交织成网，上皮下神经伸达上皮之间。肌间丛和粘膜下丛内有深染的大型多极形、卵圆形AchE阳性神经元，也有浅染的中小型圆形的AchE阳性神经元在丛内密集分布。同时还与邻近的食管壁内的神经形态作了比较。

Karnovsky-Root method was used to observe that there are abundant AchE-positive nerves in the myenteric plexus, submucosal plexus and subepithelial plexus between the fetus and the esophageal horn. The muscular plexus and intramuscular nerve fibers are particularly dense and deep-colored. Submucosa within the blood vessels and glands around the mucosa intramuscular nerve fibers interwoven into the network, between the subcutaneous nerve reaches up between the epithelium. Muscular plexus and submucosal plexus deep-stained large polypolar, oval AchE-positive neurons, there are light-stained small round AchE positive neurons densely distributed within the cluster. At the same time also with the nearby esophageal nerve morphology were compared.
