Descriptions Names[Advanced Search]

Any constituent part of the endoplasmic reticulum, the irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. A fine reticular network of membrane-limited elements that pervades the sarcoplasm of a muscle cell; continuous over large portions of the cell and with the nuclear envelope; that part of the endoplasmic reticulum specialized for calcium release, uptake and storage. The portion of sarcoplasmic reticulum devoted to calcium ion storage and calcium ion release. The region between the inner and outer lipid bilayers of the terminal cisterna envelope. This space is enriched in calsequestrin. The volume enclosed by the membranes of the sarcoplasmic reticulum. The volume enclosed by the membranes of the endoplasmic reticulum. A compartment that consists of a lumen and an enclosing membrane, and is part of an organelle.
