摘  要:
咽下神经节是昆虫腹神经索的第一个复合神经节,主要调节口器附肢的活动。本研究通过形态解剖、BrdU免疫组织化学等技术,对中华蜜蜂Apis cerana cerana咽下神经节的组织结构和胚后发育过程进行了比较研究。结果表明:中华蜜蜂的咽下神经节由上颚、下颚和下唇3个神经节组成。在胚后发育过程中,细胞增殖的活跃期主要集中在预蛹和蛹发育的第1天,增殖活动一直持续到蛹发育的第4天结束。根据神经胶质细胞的位置和形态,咽下神经节中的神经胶质可分为3种类型——表面神经胶质、皮层神经胶质和神经纤维网神经胶质。本研究为蜜蜂神经系统的发育和功能研究提供了理论基础。

摘  要:
The suboesophageal ganglion(SOG) receives sensory projections from the nerves of the mouthparts and gives rise to motorneurons that supply muscles of the mouthparts.The anatomical organization and postembryonic development of the SOG in the Chinese honeybee,Apis cerana cerana,was comparatively studied by using anatomy and immunohistochemical method(5-bromo-2-deoxyuridine,BrdU incorporation).The results showed that the SOG of the honeybee is composed of mandibular,maxillary and the labial neuromeres.During postembryonic development of the SOG,extensive proliferation in the SOG could be detected only within a narrow time window from prepupa to day 1 of pupal development during metamorphosis.Proliferative nuclei disappeared during day 4 of pupal development.In the SOG of A.cerana cerana,glial cells can be classified into three categories based on the position of their cell bodies,and cell morphology:surface associated glia,cortex associated glia and neuropil associated glia.This study provides an essential foundation for studying development and function of nervous system of honeybees.
