黄脸油葫芦中枢神经系统的组织解剖学研究

应用解剖镜和光镜观察了黄脸油葫芦(Teleogryllus emma (Ohmachi and Matsuura))中枢神经系统的组织解剖学结构，并对脑和各体神经节的组织学结构进行了比较．结果表明，黄脸油葫芦的中枢神经系统由脑、食道下神经节和腹神经索组成；前、中、后脑分化明显，腹神经索包括三对胸神经节、五对腹神经节及纵贯各神经节的神经索；脑和各体神经节的组织学结构相似，由外向内依次是神经鞘、神经细胞层和髓质层；脑的髓质层复杂，其中含有四种由神经细胞球体和神经纤维束形成的脑体，一对蕈状体、一个脑桥体、一个中央体及一对脑腹体。

Central nervous system morphology of Teleogyllus emma

The central nervous system of Teleogyllus emma (Ohmachi and Matsuura) consist of brain,suboesophageal ganglion and ventral nerve-cord. There are obvious differences among procerebrum,deutocerebrum and tritocerebrum. Ventral nerve-cord consists of three pairs of thoracic ganglia, five pairs of abdominal ganglia and connectives between ganglia. The structure characters of the brain and the ganglia are similar. Froming outside to inside are Nerve sheath, Neurocyte and Neuropile. The Neuropile of procerebrum consisting of a pair of corpora pedunculata, pars intercerabralis, corpuscentrale and a pair of corpora ventral is more complex than other ganglia.
