Patiria miniata
Biological Process
fertilization
Cellular Component
nuclear chromatin
Phosphorus has a characteristic electron energy loss with an edge at 160 eV. The Zeiss 902 electron microscope permits images to be recorded at different energy losses which can be digitized and proce...

Thyone briareus
Biological Process
fertilization
Cellular Component
acrosome
The movie shows, in real time, the explosive acrosomal reaction of Thyone (sea cucumber) sperm. The field shows several sperm heads (bright contrast) with tails of some in the plane of focus. From the...

NCBI Organism Classification
Phodopus
Biological Process
single fertilization
Cellular Component
microvillus membrane
Scanning electron micrograph showing in vitro fertilization of a hamster oocyte. The sperm head, near the center of the field of view, is engulfed by the microvilli on the surface of the oocyte membr...

Phodopus
Biological Process
single fertilization
Cellular Component
microvillus membrane
Scanning electron micrograph showing a lateral view of sperm penetration of a hamster oocyte during vitro fertilization. As the membrane of the sperm head fuses with that of the oocyte, the microvill...

axoneme
Figure 330 from Chapter 14 (Sperm Flagellum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. This electron micrograph shows a transverse section through the principle piece of Chinese hamster spermatoz...

microtubule-based flagellum part
Figures 344 (upper) and 345 (lower) from Chapter 14 (Sperm Flagellum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Cross sections of the sperm tail of the Cecidomyid fly, Monarthropalpus buxi. Excep...

Cellular Component
zona pellucida
Light micrograph of human ovum (egg) and sperm. The ovum is much larger than the sperm and is surrounded by protective cumulus cells around the outside surface (yellow). The membrane surrounding the o...

Cellular Component
male germ cell nucleus
Echinoderm sperm nuclei are unusual in that chromatin fibers are clearly seen, allowing their diameter to be accurately determined. Here, sperm from the starfish P. miniata were treated to remove the ...
