腔肠动物平衡感觉器官结构的研究进展

本文概述了腔肠动物的平衡感觉器官结构：刺胞动物掌状伞形螅（Corymorpha palma）固着器末端的无纤毛平衡囊、软水母（Leptomedusae）钟形伞缘的开放型和封闭型平衡囊、筐水母（Narcomedusae）外伞表面外伞神经环上方边缘有感觉棍的间囊水母（Aegina）和有感觉乳突及感觉棍的嗜阳水母（Solmissus）的平衡囊、硬水母（Trachymedusae）外伞神经环上方边缘的平衡囊、钵水母（Scyphozoa）伞缘的感觉棍和立方水母（Cubozoa）伞缘稍上方的感觉棍，栉水母（Ctenophore）反口面中央的平衡囊或顶器官。本文内容对理解其他水生无脊椎动物的平衡感觉器官的结构及功能有重要意义，同时也可能作为对现行动物学相关教材内容的有益补充。

Equilibrium Sensory Organ Structures in Coelenterate

This paper provides an overview of the equilibrium sensory organ structures in Coelenterate: Statocyst lacking cilia at the end of the holdfast in fairy palm Corymorpha palma. Open and closed type statocysts of Leptomedusae lie on the bell margin. The statocysts of Narcomedusae lie on the exumbrellar surface just above the exumbrellar nerve ring, with a sensory club (Aegina) and a sensory papilla carrying a sensory club (Solmissus). The statocysts of Trachymedusae lying around the margin above the exumbrellar nerve ring. Rhopalia on the edge of the umbrellar of Scyphozoa and rhopalia slightly above Cubomedusae umbrella edge. Statocysts or apical organs of Ctenophores located at the aboral end of the bodies. This article has great significance to understanding the structures and functions of equilibrium sensory organs of other aquatic invertebrates, and it might also be a useful supplement to the current zoological textbooks.
