Scanning electron micrograph montage of cultured HeLa cells. This image is a montage of six overlapping fields of view, each photographed at 2,231x with a 17.8mm working distance and an accelerating v...

Drosophila melanogaster thoracic tergotrochanter muscle from a four week-old wild-type animal. A longitudinal section of myocyte is displayed. Sections of parallel myofibrils are seen with distinguish...

Collagen fibrils in the basal plate of Fundulus heteroclitus scales. The basal plate is made of thick collagen fibrils about 100 nm in diameter, which are organized into a plywood-like structure. Note...

Transmission electron micrograph of mouse cardiac muscle (ventricle). The image illustrates the myofibrils as well as a sarcomere in the area of fibrils between the two Z-lines. Z-lines link actin fi...

Transmission electron micrograph showing adjacent muscle fibers from the ventricle of a mouse cardiac muscle. This image shows the organization of muscle tissue, nucleus, cell walls and blood vessels...

Collagen fibrils and mineralization in the external layer of Fundulus heteroclitus scale. The external layer is the second of three layers closest to the dermis of an elasmoid. It is composed of thin ...

Transmission electron micrograph of the periphery of an atria mouse cardiac muscle. This micrograph shows how rich cardiac tissue is with mitochondria reflecting its greater dependence on cellular re...

Cell junctions formed between adjacent epidermal cells in Fundulus heteroclitus scales. Desmosomes line the membranes of two epidermal cells. A vast network of intermediate filaments and microfilament...

Drosophila melanogaster thoracic indirect flight muscle from a four week-old wild-type animal. Here, an oblique section of myocyte is displayed. Sections of parallel myofibrils are visible between den...

Transmission electron micrograph showing the nucleus of a mouse cardiac tissue with nucleolus. At the center of the image is a large structure called the nucleus which is a membrane-limited compartmen...
