狮子的植物性神经解剖

Anatomy of Vegetative Nerves in Two Lions

对２头狮子的植物性神经的干、神经节和神经丛的形态结构及分布进行了解剖观察。发现狮子的交感神经系中颈前神经节的体积达３４ｍｍ×５ｍｍ×３ｍｍ：左右侧均未发现独立的颈中神经节；星状神经节由前４个胸神经节合并而成；胸部交感干的灰白交通支非常易于区分；在副交感神经系中，主要观察了迷走神经的始末，尤其是颈静脉神经节和结状神经节的形态与位置；迷走神经各段的分支及分布等，各神经节的节后纤维的分布与马属动物基本相似。

The morphoses and positions were dissected and observed of nerver trunks,neu-roganglions and nervous plexus of the vegetative nervous systems in two lions.Measuring34 × 5×3mm,the anterior cervical neuroganglions of the sympathetic sytqtems in the lionswere found to be relatively larger than those in other animals.Middle cervical neurogan-glions were not found on both right and left sides.Stellate neuroganglions were merged in-to by tle first four thoracic neuroganglions。Greyish white;ympathetic branches to thethoracic sympathetic trunks were very easy to differentiate.Observed in the parasympa-thetic nervous systems were the beginning and end of vagus and the morphosis and posi-tions of jugular venous ganglions and nodular ganglions,branches to each section of vagusand their distribution.The distribution of the postganglionic fibers for each neuroganglionwas identical with that in horses.
