| 摘 要： | 采用活体解剖和组织切片技术对曼氏无针乌贼精荚器结构及精荚形成过程进行了初步研究。结果表明,曼氏无针乌贼精荚器由输精管、粘液腺、放射导管腺、中被膜腺、外被膜腺、硬腺、终腺等腺体组成,依靠结缔组织相连,并外披被膜形成椭圆形囊状结构;精子经输精管输送到粘液腺内,形成精子团;在放射导管腺内,精荚的放射导管结构和外膜、中膜、内膜...

| Abstract: | Fine structure of spermatophoric organ and formation of spermatophore in Sepiella maindroni were studied by using morphologic observation and histological methods. The results show that spermatophoric organ in S. maindroni is a cystic structure,which is consist of vas deferens, mucilaginous gland, ejaculatory apparatus gland, middle tunic gland, outer tunic gland, hardening gland, and finishing gland. Sperms from spermary are transported in vas deferens. Embryonic forms of sperm mass are shaped in the mucilaginous gland. Ejaculatory apparatus, inner tunic, inner membrane, middle membrane, and outer membrane are formed in ejaculatory apparatus gland. Middle tunic of spermatophore is assembled in middle tunic gland. Outer tunic of spermatophore is assembled in outer tunic gland. Complete spermatophores are found in hardening gland and finishing gland in turn, and mature in spermatophoric sac through spermatophore duct. This paper discusses the differences on fine structure of spermatophoric organ and formation of spermatophore between Sepiella maindroni and other cephalopods. |
