This paper explains how parallel sheets of endoplasmic reticulum are connected. The existence of these sheet stacks and their function in synthesis of membrane and secreted proteins has been known for more than 60 years. Three-dimensional reconstructions from serial section electron micrographs from the mouse salivary gland show that the sheets are connected by twisted membrane surfaces with helical edges. The overall structure resembles a parking garage, in which the different levels are connected by helicoidal ramps. Theoretical calculations show that this structure minimizes the elastic energy of sheet edges and surfaces and allows dense packing of this organelle in the restricted space of a cell.
