Colorized transmission electron micrograph (TEM) of rough endoplasmic reticulum (ER) from an acinar cell in the pancreas.

Classic early transmission electron micrograph of a thin section of guinea pig pancreas showing ribosome-studded rough endoplasmic reticulum. Image made available by James D. Jamieson and the Depart...

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...

The pellicular pore consists of the invaginated plasma membrane that penetrates the alveolus as well as the epiplasm and ends as a clathrin-coated pit. TEM taken on 3/14/72 by R. Allen with Hitachi HU...

This high resolution micrograph may show important features involved in calcareous plate formation within the alveoli that underlie the plasma membrane in Coleps. Densities are seen on the inner alveo...
