摘要
本文对高原鼠鼠兔脑神经的起源、行程、支配部位作了详细观察,并同亲缘关糸较近的家兔和大鼠者进行了比较,简要讨论了脑神经的形态和习性及分类系烧的关系.观察结果如下:1.高原鼠免的脑神经与家兔和大鼠者相比,同家兔更相似.2.从高原鼠兔的习性和脑神经的分布特点,说明神经分布与器官大小及机能作用成正比.3.交感神经有分支到第Ⅳ脑神经和第Ⅴ脑神经的眼支及上颌支.
This paper deals with the Observation on the origin,run,distributionof cranial nerve of plateau pike and compares its cranial nerve with thatof rabbit and rat.It also discusses the correlation between morphology ofcranial nerve,habits and taxonomic system of plateau pika.The resultsare as follows.1.The cranial nerve of plateau pika is much more similar to cranialnerve of rabbit than that of rat.2.The habits and nervous distribution of plateau pika show that thedistribution of the cranial nerve of animal is direct in the ratio with si-ze and function of its organ.3.The fine branches of the sympathetic nerve join the 6th cranialnerve and ramus ophthalmicus and maxillaris of the 5th cranial nerve.
