摘要:
AbstractDevelopment 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 themaxillomandibular 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 su
