The Acrosome Reaction in Mytilus Edulis
The intact acrosome of the Mytilus edulis spermatozoon consists of a conical vesicle, the basal side of which is deeply invaginated so that the whole vesicle forms a sheath around a very slender axial rod, about 2.7 micro long, inserted in a tube passing through the nucleus. The annular base of the acrosomal vesical is filled with a homogeneous substance; the outer wall of the vesicle is lined ...
متن کاملGrowth of mussels (Mytilus edulis
Mussel seed, obtained from the intertidal zone and permanently immersed collector ropes, was cultivated on ropes suspended from three rafts located at three different sites within the Ria de Arousa (Galicia, NW Spain). Sites were characterized by different levels of phytoplankton availability. The source of seed stock had a marked influence upon subsequent mussel growth; seed originating from c...
متن کاملThe Acrosome Reaction In
Suspensions of Mytilus edulis eggs were fixed with osmium tetroxide at various intervals between 1 and l0 seconds after heavy insemination, and sectioned for electron microscopy to follow the natural process of acrosome reaction in the spermatozoa around the eggs. Sperm suspensions were also fixed after the addition of I0 per cent by volume of M/3 calcium chloride. Within the first second after...
متن کاملObservations on the ligament of Mytilus edulis.
1. The ligament of Mytilus edulis is situated between the valves of the shell imme diately below the dorsal margin and may be divided into two main layers, the inner and the outer, the principal features of which appear to correspond with those of other bivalves. 2. The outer layer is subjected to a tensile strain transverse to the longitudinal plane of the shell, which is imposed by the additi...
متن کاملThe exhalant jet of mussels Mytilus edulis
The exhalant jet flow of mussels in conjunction with currents and/or other mussels may strongly influence the mussels’ grazing impact. Literature values of mussel exhalant jet velocity vary considerably and the detailed fluid mechanics of the near-mussel flow generated by the exhalant jet has hitherto been uncertain. Computational modelling of this phenomenon depends on knowledge of the velocit...
