The internal space of the endoplasmic reticulum is called the cisternal space, or lumen, which is part of the "rough endoplasmic reticulum." The lumen is the staging area where the final modifications of protein synthesis take place, and its quality is analysed before releasing it for transportation to it's intended destination.

What body part is similar to the endoplasmic reticulum?
The endoplasmic reticulum is located inside the cells in people's bodies. The endoplasmic reticulum (ER) is repsonible for the production of the protein and lipid components of most of the cell's organelles.
What is endoplasim reticulum?
the endoplasmic reticulum (ER) is repsonible for the production of the protein and lipid components of most of the cell's organelles. The ER contains a great amount of folds - but the membrane forms a single sheet enclosing a single closed sac. This internal space is called the ER lumen. The ER is additionally responsible for moving proteins and other carbohydrates to the Golgi apparatus, to theplasma membrane, to the lysosomes, or wherever else needed. There are two types of ER - rough, which is coated with ribosomes, and smooth, which isn't. Rough ER is the site of protein synthesis. The smooth ER is where the vesicles carrying newly synthesized proteins (from the rough ER) are budded off.
What does the smooth ER do in a animal cell?
The smooth endoplasmic reticulum has functions in several metabolic processes, including synthesis of lipids, metabolism of carbohydrates and calcium concentration, and attachment of receptors on cell membrane proteins. It is connected to the nuclear envelope. Smooth endoplasmic reticulum is found in a variety of cell types (both animal and plant) and it serves different functions in each. It consists of tubules and vesicles that branch forming a network. In some cells there are dilated areas like the sacs of rough endoplasmic reticulum. The network of smooth endoplasmic reticulum allows increased surface area for the action or storage of key enzymes and the products of these enzymes. The smooth endoplasmic reticulum is known for its storage of calcium ions in muscle cells.The sarcoplasmic reticulum is a special type of smooth ER found in striated muscle. The only structural difference between this organelle and the smooth endoplasmic reticulum is the medley of protein they have, both bound to their membranes and drifting within the confines of their lumens. This fundamental difference is indicative of their functions: the smooth ER is built to synthesize molecules and the sarcoplasmic reticulum is built to store and pump calcium ions.The sarcoplasmic reticulum contains large stores of calcium, which it sequesters and then releases when the cell is depolarised. This has the effect of triggering muscle contraction.
Why is not the mitochondrian classified as a part of endomembrane system?
Its structure is not derived from the ER In contrast to organelles of the endomembrane system, these organelles have at least two membranes separating the innermost space from the cytosol. Their membrane proteins aren't made by the endoplasmic reticulum, but by ribosomes in the cytoplasm and in the organelle itself.
What is the rough endoplasmic reticulum in the synthesis of?
During translation, the mRNA leaves the nucleus and attaches onto a ribosome on the rough endoplasmic reticulum. Once attached, the ribosome translates the mRNA into amino acids, which fold into a protein.
What is a function of a endoplasmic reticulum?
The endoplasmic reticulum is a network of membrane- covered channels that look like a fold of a fan or accordion. Being folded means the endoplasmic reticulum has a large surfaced area in a small space.
What is the structure of the reticulum?
Endoplasmic reticulum has network of cisternae. Cisterna is phospholipid membrane that encloses a space (lumen) from cytosol. Cytosol contains water and macromolecules. Cisternae are held together by cytoskeleton.Endoplasmic reticulum containing ribosomes (small spherical organelles) on its membrane is called rough endoplasmic reticulum.

The endoplasmic reticulum is an extension of what?
The endoplasmic reticulum (ER) is thought to be an extension of the nuclear membrane. This structure is seen to connect the nuclear membrane to the cell membrane. When viewed under high magnification, this organelle is seen to encompass the entire cytoplasmic space between the nucleus and cytoplasm.
What is the function the endoplasmic reticulum in a cell?
what does a rough endoplasmic reticulum do for a cell
Structure and function of the nuclear envelope?
the structute of the nuclear envelope is one of the stages in the cell cycle called called the telophasethe structute of the nuclear envelope is one of the stages in the cell cycle called called the telophase
How are the Golgi body and endoplasmic reticulum different?
Well...The primary function of the Golgi apparatus is to process and package macromolecules, such as proteins and lipids, after their synthesis and before they make their way to their destination; it is particularly important in the processing of proteins for secretion. The Golgi apparatus forms a part of the cellular endomembrane system.And of courseEndoplasmic reticulum is a network of tubules, vesicles and sacs that are interconnected. They may serve specialized functions in the cell including protein synthesis, sequestration of calcium, production of steroids, storage and production of glycogen, and insertion of membrane proteins. The first part of this presentation will focus on rough endoplasmic reticulum which gets its name from the presence of ribosomes on its surface.The endoplasmic reticulum (ER) is repsonible for the production of the protein and lipid components of most of the cell's organelles.

What is the internal space of a blood vessel called?
called lumen
What is a occupies space between cell membrane and nucleus?
what is nubleus? I guess there's typing error there so I'll take it as nucleus. Pertaining to your question, there are many organelles that occupies the space. Eg.Cytoplasm, endoplasmic reticulum, vacuoles, etc.
