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...

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...

of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Scanning electron micrograph of the epidermal surface of the flatfish sole Parophrys detulus shows a labyrinth of surface ridges. Image from Fahrenbach,...

Scanning electron micrograph of the lumenal surface of the toad bladder shows the boundaries of four polygonal squamous epithelial cells surrounding a mitochondrial-rich cell bearing short globular mi...

Scanning electron micrograph of the epidermal surface of the Pacific coho salmon. Ridge-like folds of the plasmalemma, called microplicae, display a labyrinth pattern across the surface, and a circum...

Scanning electron micrograph of the epidermal surface of lamprey larvae. A row of microvilli outline the polygonal borders between cells, while short microvilli cover the external surface in a reticu...

The final stages of cell division is captured in the scanning electron micrograph. Two daughter cells are still interconnected by slender strands of membrane (white arrow at center of image). Lamell...

Liver sinusoid of a Brown Rat with fenestrated endothelial cells. Sinusoidal width is about 5 microns. Original magnification is 10,000x . Note the microvilli of hepatocytes in the space of Disse exte...

Fenestrae of a Brown Rat arranged in sieve plates. Original magnification is 20,000x, a good indication of liver sinudosial endothelial cells (LESCs).
