Related to endoplasmic reticulum: Smooth endoplasmic reticulum

endoplasmic reticulum

A membrane network within the cytoplasm of cells involved in the synthesis, modification, and transport of cellular materials.

endoplasmic reticulum

(Biology) an extensive intracellular membrane system whose functions include synthesis and transport of lipids and, in regions where ribosomes are attached, of proteins

endoplas′mic retic′ulum

a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum), involved in the transport of materials..

en·do·plas·mic reticulum

A network of membranes within the cytoplasm of many cells that is important in protein synthesis and involved in the transport of cellular materials. All organisms except bacteria have at least one endoplasmic reticulum in their cells. See more at cell.

endoplasmic reticulum

A system of internal membranes in a cell.

en·do·plas·mic re·tic·u·lum

n. retículo endoplásmico, sistema de canales en los cuales se llevan a cabo las funciones de anabolismo y catabolismo de la célula.

This membrane system, the endoplasmic reticulum (ER), provides the scaffolding to which the ribosomes are attached to the ER.
As the development of the oocyte continues and its size increases, basophylia diminishes and more membrane organelles, like the rough endoplasmic reticulum (RER) and the Golgi complex, begin to be apparent.
The rough endoplasmic reticulum is well developed, revealing dilated cisternae distributed concentrically (Figures 1H and I).
This potentially explains why the outer leaf of the nuclear membrane is contiguous with the endoplasmic reticulum, but also postulates the existence of a complex organelle that is not found in extant archaea.
