| 摘 要： | 中国对虾第一触角由三个触角节和内、外两触鞭构成,化感刚毛着生于外鞭基部片状隆起的腹面,成横排排列,每环节两排。化感刚毛壁薄、中空、末端开孔通外界。第一触角外鞭神经有分支分布于化感器,支配化感刚毛的是多神经元组成的感觉细胞丛,其神经元细胞体集中处成纺锤状,树突轴突集中成索状,皆由围鞘包被。树突集合体从管孔穿入化感刚毛腔,轴突与外鞭神经连接。内鞭基部约33节具羽状刚毛,徒腹面覆盖化感刚毛,具保护化感刚毛作用。

| Abstract: | The antennules of Penaeus chinensis are consisted of three basal segments and two eJongare destal rami.The asthetasc hair is long,thin,cylindrical in shape,and has an apical pore.These hairs occur in transverse rows on the ventral surface of a piece like processes,that project from the base of the outer ramus.Each of these hairs was innervated by a considerable collection of neurons,whose cell bodies were gathered in spindle-shaped.The collection of dendrit-es that originates from each bunch of sense cells projects into a lumen whithin the hair.The collection of axons extends centrally to join the antennular nerve.The afferent axons,the cell bodies and the dendrite are all enclosed in a sheath |
