Electron micrograph of an unmyelinated nerve Schwann cell from a rat tongue. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of Medicine.

Transmission electron micrograph of nerve cell terminals on medulla dendrites. The body of the dendrite (lower part of image) contains aligned microtubules (neurotubule). Synapses are seem on the den...

Transmission electron micrograph of a nerve cell synapsing on a dendrite. The synapse contains many synaptic vesicles and a cluster of mitochondria. Note that this very early (1953) micrograph is pr...

Early transmission electron micrograph of a thin section of the ribosome-studded rough endoplasmic reticulum of guinea pig pancreas. The ribosomes (small dots) were originally called Palade particles...

Early transmission electron micrograph of a thin section of a secretory cell from guinea pig pancreas illustrating vesicle trafficking between the rough endoplasmic reticulum and Golgi apparatus (uppe...

An electron micrograph of the unicellular flagellate protists Euglena. The image shows a grazing section of a cell illustrating the spiral ridged pellicle. Micrograph made available by James D. Jamie...

An electron micrograph showing a portion of the single chloroplast of the unicellular green alga Chlamydomonas, an organism extensively used in the Siekvevitz/Palade laboratories at the Rockefeller t...

Transmission electron micrograph of desmosomes (macula adherens)in the junctional complex between cells in frog skin. The upper desmosome is cut obliquely and appears much wider than the lower (vertic...

Transmission electron micrograph of liver cells from a 3-day old rat showing extensive smooth and rough endoplasmic reticulum, and glycogen (dark rosettes). Image made available by James D. Jamieson a...
