Quick-frozen deep-etched preparation of skeletal muscle tissue shows the muscle fiber and associated extracellular components. The basement membrane (labeled basal lamina) lies adjacent to the undulat...

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...

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 row of large IMPs bordering parts of the plates are visible. Two parentheses-shaped empty trichocyst docking sites are also present and one ring surrounding pits where the rosette IMPs have been rem...
