在过去的十年中，对无脊椎动物神经系统和肌肉组织发育的研究变得更加复杂和众多，并已证明为生物体的进化史提供了新的见解。为了提供新的形态发生数据后鳃腹足类，我们研究了神经肌肉的发展裸鳃Aeolidiella stephanieae Valdéz，2005年使用免疫细胞化学以及F-肌动蛋白标记结合共聚焦激光扫描显微镜（cLSM）。Aeolidiella stephanieae的个体发育可分为8个阶段，每个阶段可分别通过特征性的形态和行为特征以及神经系统和肌肉系统的特定特征来识别。A.幼虫的神经系统。千金藤亚科包括一个顶端器官、发育中的中央神经节和与幼虫的帆、足和后部内脏部分有关的外周神经元。第一个多巴胺能和FMRFamidergic神经结构出现在顶端器官，表现出一系列的三个感觉，瓶形和两个非感觉，圆形神经元，完全消失前变态。变性后的中枢神经系统（CNS）变得集中，口神经节与将来的神经根原基一起发育，而口腱神经节则没有。千金藤亚科以幼虫牵开肌开始，随后是辅助幼虫牵开肌、软膜或原轮肌和足牵开肌，它们在变态期间一起退化，并且成体肌肉复合体重新形成。stephanieae的Aeolidiella包括幼虫和变态后的神经和肌肉系统的特征，代表了软体动物甚至是担轮动物的地面平面。G.存在原滑车或软腭肌环）。一方面，A.千金藤亚科具有所有裸鳃类动物所共有的一些特征，如中枢神经系统的后变性浓缩、具有咽神经节和缺乏口腱神经节以及成体肌肉复合体的重新形成。另一方面，该属的顶器的结构和排列与其他新腹足类和后鳃腹足类相似，支持它们的姐妹群关系。
Studies on the development of the nervous system and the musculature of invertebrates have become more sophisticated and numerous within the last decade and have proven to provide new insights into the evolutionary history of organisms. In order to provide new morphogenetic data on opisthobranch gastropods we investigated the neuromuscular development in the nudibranch Aeolidiella stephanieae Valdéz, 2005 using immunocytochemistry as well as F-actin labelling in conjunction with confocal laser scanning microscopy (cLSM). The ontogenetic development of Aeolidiella stephanieae can be subdivided into 8 stages, each recognisable by characteristic morphological and behavioural features as well as specific characters of the nervous system and the muscular system, respectively. The larval nervous system of A. stephanieae includes an apical organ, developing central ganglia, and peripheral neurons associated with the velum, foot and posterior, visceral part of the larva. The first serotonergic and FMRFamidergic neural structures appear in the apical organ that exhibits an array of three sensory, flask-shaped and two non-sensory, round neurons, which altogether disappear prior to metamorphosis. The postmetamorphic central nervous system (CNS) becomes concentrated, and the rhinophoral ganglia develop together with the anlage of the future rhinophores whereas oral tentacle ganglia are not found. The myogenesis in A. stephanieae begins with the larval retractor muscle followed by the accessory larval retractor muscle, the velar or prototroch muscles and the pedal retractors that all together degenerate during metamorphosis, and the adult muscle complex forms de novo. Aeolidiella stephanieae comprises features of the larval and postmetamorphic nervous as well as muscular system that represent the ground plan of the Mollusca or even the Trochozoa (e. g. presence of the prototrochal or velar muscle ring). On the one hand, A. stephanieae shows some features shared by all nudibranchs like the postmetamorphic condensation of the CNS, the possession of rhinophoral ganglia and the lack of oral tentacle ganglia as well as the de novo formation of the adult muscle complex. On the other hand, the structure and arrangement of the serotonergic apical organ is similar to other caenogastropod and opisthobranch gastropods supporting their sister group relationship.
