Figures 338 (upper) and 339 (lower) from Chapter 14 (Sperm Flagellum) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Transverse sections through midpiece and principal piece of several sperm from the n...

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...

The movie shows two sequences that begin with an unfertilized Arbacia (sea urchin) egg in which the contents have been stratified using the centrifuge polarizing microscope (CPM) developed by S. Inoue...

This electron micrograph shows a cross section through the midpiece of opossum sperm. Filamentous cytoplasm underlies a scalloped membrane with regular variations in thickness, which gives it a corrug...

A confocal micrograph of a human embryo, with some remaining sperm cells, about five days after fertilization. The nuclei of both the sperm and cells of the embryo are stained purple, the tails of the...
