Endoplasmic reticulum is a network of membrane bound cavities vesicles and tubules distributed throughout the cytoplasm. It is concerned with the biosynthesis of proteins and lipids It is more concentrated in the endoplasm than in the ectoplasm. Ultrastructure of Endoplasmic Reticulum.

All the three structures of endoplasmic reticulum are bounded by a thin membrane of 50 to 60 A thick. Like plasma membrane nucleus etc its membrane is also formed of three layersouter and inner dense layers are composed of protein molecules and the two middle thin and transparent layers are of phospholipids Robertson 1959. In conclusion endoplasmic reticulum stress confirmed at ultrastructure level plays an important role in pathogenesis of HFD-induced hepatic steatosis.

HNF4α downregulation as well as increased expression of hs-CRP and TNF-α enforce the concept of interplay between ER stress hepatic subclinical inflammation and disturbed gene expression regulation in the pathogenesis of HFD-induced hepatic.

All three endoplasmic reticulum structures are surrounded by a thick membrane. The membrane also consists of three layers outer and inner thick layers consist of protein molecules and phospholipids are the two mid thin and translucent layers.

The appearance ultrastructure and function of endoplasmic reticulum. Endoplasmic reticulum ER provides a surface for the synthesis of different molecules needed in a cell. It can also store and transport these materials.

The molecules involved depend on the type of ER. Rough Endoplasmic Reticulum Structure. The rough endoplasmic reticulum is named so because of its appearance.

It is a series of connected flattened sacs having several ribosomes on its outer surface hence the name. It synthesizes and secretes proteins in the liver hormones and other substances in. It was discovered by Porter 1945 as fine recticulum in endoplasm of cells and named as endoplasmic reticulum ER.

It is a complex interconnecting system of flattened membrane-surrounded channels and vesicles cisternae that spreads throughout the cytoplasm of eukaryotic cells. The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in plant and animal cells. The two regions of the ER differ in both structure and function.

Rough ER has ribosomes attached to the cytoplasmic side of the membrane. Molecular structure The membrane of ER are composed of two layers of phospholipid molecules sandwiched by two layers of proteins molecules like other membrane in the cell wall. Types The endoplasmic reticulum is of two types.

2014 May 15306 10F1190-7. Endoplasmic reticulum continuous with the outer membrane of the nucleus it is a three-dimensional sheet like structure formed of flattened sacks called cisternae. There are two kinds of ER smooth ER and rough ER.

Smooth endoplasmic reticulum lacks ribosomes on the surface. In semithin sections dysmorphic oocytes displayed a cytoplasm abundant in large smooth endoplasmic reticulum SER vesicles and mitochondria clusters containing also a central large aSERT that measured 264 64 μm. The ultrastructure of MII from normal and dysmorphic cohorts presented a homogeneous distribution of organelles.

The light epithelial cell has an extensive network of endoplasmic reticulum which is characteristically arranged in a baso-apical direction. The connections between the inner surface of the plasmalemma and the endoplasmic reticulum were observed as were connections between the Golgi complex and the endoplasmic reticulum. 37 Full PDFs related to this paper.
