Reticulum (anatomy) The internal mucosa has a honeycomb shape. When looking at the reticulum with ultrasonography it is a crescent shaped structure with a smooth contour. The reticulum is adjacent to the diaphragm, lungs, abomasum, rumen and liver.The heights of the reticular crests and depth of the structures vary across ruminant animal species.natomically it is considered the smaller portion of the reticulorumen along with the rumen. Together these two compartments make up 84% of the volume of the total stomach. The rumen is located at the base of the esophagus.

What is a Tenaculum? A tenaculum is a surgical instrument which is used to grasp and hold tissues. The tenaculum is a form of locking forceps, designed to hold itself in place once it has been locked, and it can be used to hold tissues steady for surgical procedures, to hold tissues out of the way, or to grasp tissues for the purpose of manipulating them.

Endoplasmic reticulum Endoplasmic reticulum. The endoplasmic reticulum (ER) is a type of organelle in eukaryotic cells that forms an interconnected network of flattened, membrane-enclosed sacs or tube-like structures known as cisternae. The membranes of the ER are continuous with the outer nuclear membrane.

Endoplasmic Reticulum Endoplasmic Reticulum. The endoplasmic reticulum is a multifold membranous structure within eukaryotic cells which plays a major role in the synthesis of the complex molecules required by the cell and the organism as a whole.he ribosomes on the rough endoplasmic reticulum manufacture proteins which enter the channels of the endoplasmic reticulum and move to places where they can create pockets.

- The endoplasmic reticulum is a series of folded vesicles that provide a surface for many cellular activities, including the metabolism of carbohydrates and protein production in ribosomes. There are two types of endoplasmic reticulum, the smooth endoplasmic reticulum and the rough endoplasmic reticulum. The smooth endoplasmic reticulum is used in the storage and production of steroids and lipids; the rough, in the production and transport of proteins.

Endoplasmic Reticulum Endoplasmic Reticulum Structure. Endoplasmic reticulum is an extensive membrane network of cisternae (sac-like structures), which are held together by the cytoskeleton. The phospholipid membrane encloses a space, the lumen from the cytosol, which is continuous with the perinuclear space.

Endoplasmic Reticulum: Structure and Function The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in the cell. There are two regions of the ER that differ in both structure and function. One region is called rough ER because it has ribosomes attached to the cytoplasmic side of the membrane. The other region is called smooth ER because it lacks attached ribosomes. Typically, the smooth ER is a tubule network and the rough ER is a series of flattened sacs. The space inside of the ER is called the lumen.

Endoplasmic Reticulum Endoplasmic Reticulum shortly called as ER is the essential part of a cell. ER is closely associated with other organelles of the cell like ribosomes, DNA, RNA and golgi bodies.ER is responsible for creating network of membrane tissue covering the cell.henever the ribosomes present in the ER gets filled up with amino acids which is a protein it squeezes off the vesicle which in turn will enter into the golgi bodies for later usage.

The ER comes in two different morphological forms: smooth endoplasmic reticulum (sER) and rough endoplasmic reticulum (rER). The primary function of the sER is to serve as a platform for the synthesis of lipids (fats), carbohydrate (sugars) metabolism , and the detoxification of drugs and other toxins.

What is 'Endoplasmic Reticulum'? · just now. Report Abuse. A membrane network within the cytoplasm of cells involved in the synthesis, modification, and transport of cellular materials. Endoplasmic reticulum is a network of tubules, vesicles and sacs that are interconnected.ndoplasmic Reticulum is a fine network of tubular structures that crisscrosses the cellular cytoplasm. Some of this endoplasmic reticulum connects the nuclear membrane to the cell membrane: thus, it serves as a chennel for the transport of materials in and out of the nucleus.
