中国对虾眼柄的神经分泌结构

研究了中国对虾眼柄神经分泌结构特征。眼柄神经分泌结构由神经分泌细胞和窦腺两部分组成。依据细胞及其核直径和细胞质特征等将神经分泌细胞分为６种类型，它们多以集群方式分布，少数则分布较为分散。窦腺位于眼柄视神经节内髓外侧，呈椭圆囊状。依据神经分泌细胞轴突末梢直径和其内颗粒特征将窦腺内轴突末梢分为４种类型。

Neurosecretory Structure of Eyestalk in Penaeus chinensis

The neurosecretory structure character of eyestalk in Penaeus chinensis were reported The neurosecretory structure is composed of neurosecretory cell and sinus gland Acording to cell form,size and neuclear diameter, and cytoplasm, neuclear character, divides them into six types They distribute on the medulla interna,medulla externa and medulla terminalia in the optic ganglia Many of them distribute in concentration and others in dispersion The sinus gland is located at the outside of medulla interna Depending upon the axon terminals′ diameter and the granular character in them, four types of neurosecretory terminal are identified
