Sarcolemma of skeletal muscle prepared by a quick-freeze deep-etch method also shows the basement membrane (lamina externa, labeled here as the basal lamina) associated with the muscle fiber. This me...

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...

A high resolution image of the detail of cell surface structures. The cell is covered by the plasma membrane and outer alveolar sac membrane which is separated from the inner alveolar sac membrane by ...

The plasma membrane of Paramecium multimicronucleatum seen in a freeze fracture replica. The two rows of IMPs can be seen on the P-face of the plasma membrane that connects the plasma membrane to the ...

A high resolution image of the pellicle of Opercularia coarctata. Indentations of the plasma membrane penetrate the alveolar membranes end as coated pits. These pits are also known as pellicular pores...

This electron micrograph shows the plasma membrane of epithelial cells of the brush border of the cat intestine, obtained from a thin section parallel to the free surface. The ability to visualize ce...

Detail of cell surface structures. The cell is covered by the plasma membrane and outer alveolar sac membrane which is separated from the inner alveolar sac membrane by an extensive alveolar space. Ci...

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...

Freeze-fracture preparation of the plasma membrane from an unspecialized area composed of Sertoli cells of the guinea pig testis. With the freeze-fracture technique, tissue is rapidly frozen and crac...
