The appearance and distribution of dense-core vesicles in the stomatogastric ganglion of the spiny lobster, Panulirus interruptus, were examined using transmission electron microscopy. Following five fixation techniques, three types of dense-core vesicles were identified on the basis of size and morphology. Type-I vesicles are found in a distinct neuronal fiber system that appears to be involved in chemical transmission within the ganglion. Type-II vesicles occur in nerve processes in the ganglion, in major nerve trunks and in the perineural sheath of the nerves and ganglion. Type-III vesicles are present in all neuronal somata of the ganglion. The distinct morphology and location of the three types of vesicles suggest that their functional roles differ. Furthermore, the histochemical, biochemical and physiological data available for the stomatogastric ganglion indicate that Type-I vesicles may store dopamine.
利用透射电子显微镜检查了多棘龙虾（Panulirus interruptus）口胃神经节中致密核心囊泡的外观和分布。采用五种固定技术后，根据大小和形态鉴定出三种类型的致密核心囊泡。I型囊泡存在于一个独特的神经元纤维系统中，该系统似乎参与神经节内的化学传递。II型囊泡出现在神经节的神经突起、主要神经干以及神经和神经节的神经周鞘中。III型囊泡存在于神经节的所有神经元胞体中。这三种类型囊泡独特的形态和位置表明它们的功能作用不同。此外，口胃神经节现有的组织化学、生物化学和生理学数据表明，I型囊泡可能储存多巴胺。
