翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Streptoneury ： ウィキペディア英語版 Streptoneury Streptoneury or chiastoneury is a plesiomorphic condition present in all gastropods which is a result of an evolutionary event called torsion in which the intestines, heart, nephridia, gills, and nerve cords "twist" causing some organs to migrate from the animal's left to its right in order to accommodate the relocation of the mantle cavity close to the animal's head. Specifically, streptoneury is the crossing of the cerebrovisceral commissures caused by this torsion. In a streptoneurous animal, the right visceral nerve becomes a supraintestinal nerve (i.e., moving up from its former position along the intestines on the right side) and the left visceral nerve becomes a subintestinal nerve (i.e., moving down below the intestines and shifting to the right). The extant gastropod molluscs can be described as streptoneurous. However, some lineages, especially the opisthobranchs,〔 have reversed this twist secondarily. The term for this event is ''detorsion'', and the condition in a detorted animal— a state in which these nerves no longer cross— is called euthyneury. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Streptoneury」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
