A study on the fine structure of developing spermatozoa from the Oligochaete, Enchytraeus albidus.

摘要: Studies on the fine structure of spermatids and spermatozoa oligochaete,Enchytraeus albidus, demonstrate differentiation acrosome, flagella, nucleus associated structures. Developing are found syncytially arranged interconnected to a central nutrient mass. Acrosomal flagellar development is typical other spermatozoa. Electron densities with developing acrosomal vesicles form sub-acrosomal structures whose origin possible function compared similar in The disposition microtubules subjacent elongating acrosome basal body circumferentially around described. Comparisons made their arrangement during microtubular arrangements cells undergoing differentiation. It suggested that play role elongation these spermatids. Blebs inner nuclear membrane present intranuclear membranes elsewhere.
