赤鼻棱鳀松果体显微结构研究

Study on microstructure of pineal body of anchovy (Thrissa purava )

本文用组织学方法研究了赤鼻棱鳀（Thrissapurava）松果体的形态结构，结果表明赤鼻棱鳀有松果体窗，并有发达的松果体，感光细胞聚集成团，顶突伸入终囊腔中，终囊类型为折褶型。背囊由单层细胞构成，细胞大而圆，松果体司感光内分泌功能。

The structure and morphorology of anchovy(Thuissa purava)is studied using the tech-nique of histology. Results indicate that the fish has pineal window,its pineal body is devel-oped,the pineal endding vesicle is of fold type. The photoreceptor cells in the pineal bodyclump together and their cytoplasmic processes protrude into the pineal lumen. The dorsalsac consists of simple epithelium,of large and round cells. The pineal body has photorecepti-cal and endocrinal functions.
