Nexuses have been demonstrated between glial cell processes in the earthworm ventral nerve cord. The nexuses have been demonstrated by freeze-cleavage to be A-type neuxuses, thus demonstrating for the first time the type of nexus present in the Annelida. If the nexal cleavage pattern has physiological significance then the results suggest that physiologically the nexuses of the earthworm may be similar to those of vertebrates.
在蚯蚓腹神经索的神经胶质细胞突起之间已证实存在连接。通过冷冻蚀刻已证实这些连接为A型连接，从而首次证明了环节动物中存在的连接类型。如果连接的蚀刻模式具有生理意义，那么结果表明，从生理角度讲，蚯蚓的连接可能与脊椎动物的连接相似。
