The study of 20 excellent human embryos of the Carnegie Collection has allowed the innervation of the intestinal loop to be traced during the embryonic period proper. It follows the centrifugal sequence observed throughout in the development of the peripheral nervous system. At stage 14 or 15, the rami comunicantes and the primordium of the latero-vertebral sympathetic trunk appear. Splanchnic fibres are noted at stage 16, and at stage 17 the superior mesenteric plexus appears. Then nerve bundles progress along the superior mesenteric artery according to the following sequence: 1) Nerves fibres face the mesentery (stage 19), 2) They penetrate into the mesentery (stage 20), 3) Nerve buds move forwards and nerve fibres begin to be anchored to the muscular layer of the proximal portion of the loop, duodenum and colon (stage 21), 4) Nerve fibres are anchored to the muscular layer of the middle part of the intestinal loop (stage 22), 5) The nerve buds reach the distal part of the loop in the umbilical cord.
对卡内基研究所收藏的20个优质人类胚胎进行的研究，使得在胚胎期能够追踪肠袢的神经支配情况。它遵循在整个外周神经系统发育过程中观察到的离心顺序。在第14或15阶段，出现交通支和椎旁交感干原基。在第16阶段可注意到内脏纤维，在第17阶段出现肠系膜上丛。然后神经束沿着肠系膜上动脉按以下顺序发展：1）神经纤维面向肠系膜（第19阶段），2）它们穿透进入肠系膜（第20阶段），3）神经芽向前移动，神经纤维开始锚定在肠袢近端、十二指肠和结肠的肌肉层（第21阶段），4）神经纤维锚定在肠袢中部的肌肉层（第22阶段），5）神经芽到达脐带中肠袢的远端部分。
