The extrinsic nerve supply of the median strip of skin in the naked rhinarium of the tree shrews (Tupaia glis) was studied by means of nerve section. Experiments were designed, where the external nasal nerves, infraorbital nerves or a combination of both were sectioned. The cholinesterase and silver impregnation techniques were employed to demonstrate intraepithelial nerves, mammalian end-organs, and the dermal nerve plexus before and after denervation. These experiments have given results contrary to what was expected, as the skin in this region, which develops from the frontonasal process, was found to be supplied by the infraorbital nerves (branches of the maxillary division of the fifth cranial nerve, which is the nerve of the maxillary process) and not the external nasal nerves (branches of the ophthalmic division of the fifth cranial nerve, the nerve of the frontonasal process).
通过神经切断术对树鼩（Tupaia glis）裸鼻镜正中皮肤条带的外在神经支配进行了研究。设计了实验，切断鼻外神经、眶下神经或两者的组合。采用胆碱酯酶和银浸染技术来显示去神经前后的上皮内神经、哺乳动物终末器官和真皮神经丛。这些实验得到了与预期相反的结果，因为发现该区域由眶下神经（第五脑神经上颌支的分支，上颌支是上颌突的神经）而非鼻外神经（第五脑神经眼支的分支，眼支是额鼻突的神经）供应，该区域由额鼻突发育而来。
