Two electron micrographs of smooth muscle cells in a small artery, surrounded by a light gray zone of interspaces composed of an elastic fiber and collagen-rich basement membrane. The elastica intern...

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 a Coccolithophorid marine organism. Coccolithophorids are a group of unicellular plant plankton, which surround themselves with minute and highly structured calcite pl...

Brightfield image using an depth of fieldd showing the skeleton of a radiolarian, a single-cell protozoan with an intricate mineral skeleton. Radiolarian skeletons typically have a central capsule di...

The images in this group show electron micrographs of epidermal and mesophyll cells in thin sections of maize leaves infected with Maize mosaic virus (MMV, Rhabdoviridae). MMV virions are bullet-shape...

Schwann cells in peripheral nerves secrete a layer similar to the basal lamina called the lamina externa, boundary layer, or basement membrane. In this micrograph, the lamina externa surrounds the Sc...

The images in this group show electron micrographs of epidermal and mesophyll cells in thin sections of maize leaves infected with Maize mosaic virus (MMV, Rhabdoviridae). This tif image is of an epid...

Transitional epithelial cells of the bladder. Upper panel is an electron micrograph from thin sectioned superficial cells of the uroepithelium in the rat; lower panel shows a scanning electron microg...
