Ultrastructure of spermiogenesis and the spermatozoon in cyclophyllidean cestodes
The usefulness of the ultrastructural characters of spermiogenesis and of the spermatozoon in the interpretation of relationships in the Platyhelminthes has been widely demonstrated. The present paper provides a review and an update on the ultrastructural knowledge on spermiogenesis and on the spermatozoon in cyclophyllidean cestodes. For each family of cyclophyllideans the pattern of spermioge...
متن کاملSperm ultrastructure and spermiogenesis of Coniopterygidae (Neuroptera, Insecta).
The spermiogenesis and the sperm ultrastructure of several species of Coniopterygidae have been examined. The spermatozoa consist of a three-layered acrosome, an elongated elliptical nucleus, a long flagellum provided with a 9+9+3 axoneme and two mitochondrial derivatives. No accessory bodies were observed. The axoneme exhibits accessory microtubules provided with 13, rather than 16, protofilam...
متن کاملUltrastructure of the Hepatic Sinusoid of the Goat Capra Hircus
I t is generally agreed that the hepatic sinusoidal lining is discontinuous and that no basement membrane as such exists in the livers of rats (7-9, 14-16, 19, 20, 22), mice (5, 10, 11, 21), dogs (16), rabbits (1, 18), pig embryos (1), frogs (8), developed chick embryos (12), and humans (4, 6, 16). However, several investigators have called attention to patches of "basement membranel ike" mater...
متن کاملSpermiogenesis of Heliothis virescens (Lepidoptera: Noctuidae): An Ultrastructure Study of Eupyrene Sperm in Sterile Backcross Males
Sterile backcross (Be) males originate from the hybridization of Heliothis subflexa (Guennee) females to H. virescens (F.) males followed by recurrent backcrossing of the fertile female progeny to H. virescens males. Ultrastructural transmission electron microscope (TEM) studies of the postmeiotic maturation of eupyrene sperm cells in Be males, and comparisons with the cells in normal H. viresc...
