用抗神经丝蛋白抗体染色的鸡胚（-17 ~-27期）研究了三叉神经分支的发育。获得了以下结果。1)异位神经节短暂出现在眶上区的外胚层，被认为是残留的眼基板源性神经节。2)大部分的皮肤感觉分支的上颌神经从一个松散的树状质量的神经突，暂时称为上颌下颌网状，其中的纤维交织在一个看似随机的方式。3)三叉神经分支的生长主要与面突的发育相关;然而，观察到不同组分支之间的不规则通信，表明外周分支的地形组织在早期阶段并不刚性。4)从23期左右的眼神经，短暂的背支发达，分布在间充质空间，翼上腔，并通过附近的外胚层。它们与RR的同源性。小脑幕在人体解剖学中的地位。
Development of the trigeminal nerve branches was studied in stage -17 to -27 chick embryos stained with an antibody to neurofilament protein. The following findings were obtained. 1) Ectopic ganglia transiently appeared in the ectoderm of the supraorbital region and were considered as remnant ophthalmic-placode-derived ganglia. 2) Most of the cutaneous sensory branches of the maxillomandibular nerve arose from a loosely arborized mass of neurites, provisionally termed the maxillomandibular reticulum, in which the fibers intermingled in a seemingly random fashion. 3) The growth of the trigeminal branches was mainly correlated with the development of the facial processes; however, irregular communications between different groups of branches were observed, suggesting that topographical organization of the peripheral branches is not rigid in early stages. 4) From the ophthalmic nerve around stage 23, transient dorsal rami developed and were distributed in the mesenchymal space, the cavum epiptericum, and passed near the ectoderm. Their homology with the rr. tentorii in human anatomy is suggested.
