What is the name of the endoplasmic reticulum in a muscle cell?

sarcoplasmic reticulum
In skeletal muscle cells, SER occurs as a specialized membrane structure known as the sarcoplasmic reticulum. The sarcoplasmic reticulum is a critical storage site for calcium ions, taking up the ions from the cytoplasm.

What is the other name of ribosomes?

Ribosomes ( /ˈraɪbəˌsoʊm, -boʊ-/), also called Palade granules, are macromolecular machines, found within all cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains.

What is the name for endoplasmic reticulum in neurons?

smooth endoplasmic reticulum
The smooth endoplasmic reticulum (SER) consists of a network of tubules in the soma that connects the RER with the Golgi apparatus. The tubules can also enter the axon at its initial segment and extend to the axon terminals. The Golgi apparatus is a complex of flattened cisternae arranged in closely packed rows.

Why is it called endoplasmic reticulum?

All eukaryotic cells contain an endoplasmic reticulum (ER). Rough ER is named for its rough appearance, which is due to the ribosomes attached to its outer (cytoplasmic) surface. Rough ER lies immediately adjacent to the cell nucleus, and its membrane is continuous with the outer membrane of the nuclear envelope.

What are different types of endoplasmic reticulum write their function?

the two types of endoplasmic reticulum are : rough endoplasmic reticulum: their main function is produce proteins in the cells and ribosomes are attached to their surface. smooth endoplasmic reticulum: their main function is to produce lipids and also detoxify toxins in the body in the liver and kidney cells.

What is the other name for lysosomes?

Lysosomes are also known as suicide bags of the cell. Lysosomes work as the waste disposing of structures of the cells.

What is another name for the mitochondria?

Scientifically another name for the mitochondria is chondrosome, is also called the power house is responsible for cellular respiration and provide energy for the cells.

Do neurons have endoplasmic reticulum?

Smooth endoplasmic reticulum is present in most neurons, although it is sometimes difficult to differentiate it from the rough ER owing to the disorderly arrangement of ribosomes. Ribosomes are not associated with these membranes, and the cisternae usually assume a meandering, branching course throughout the cytoplasm.

Is there endoplasmic reticulum in axons?

In axons, ER is mainly smooth, forming a tubular network with occasional sheets or cisternae and low amounts of rough ER. It has many potential roles: lipid biosynthesis, glucose homeostasis, a Ca2+ store, protein export, and contacting and regulating other organelles.

How many types of endoplasmic reticulum and write their names?

There are two types of endoplasmic reticulum: rough endoplasmic reticulum (rough ER) and smooth endoplasmic reticulum (smooth ER). Both types are present in plant and animal cells. The two types of ER often appear as if separate, but they are sub-compartments of the same organelle.

What are the two types of ER in Class 9?

The endoplasmic reticulum is classified into two types:

  • Smooth endoplasmic reticulum.
  • Rough endoplasmic reticulum.

What are diseases caused by endoplasmic reticulum?

Endoplasmic reticulum (ER) dysfunction might have an important part to play in a range of neurological disorders, including cerebral ischaemia, sleep apnoea, Alzheimer’s disease, multiple sclerosis, amyotrophic lateral sclerosis, the prion diseases, and familial encephalopathy with neuroserpin inclusion bodies.

What are facts about endoplasmic reticulum?

endoplasmic reticulum (ER) A system of membranes within the cytoplasm of plant and animal cells. It forms a link between the cell and nuclear membranes (see cisterna ) and is the site of protein synthesis.

What does an endoplasmic reticulum look like?

The endoplasmic reticulum looks like a system with membranes that form cavities, flat cisterns and non-lamellar, round structures.

How do you describe endoplasmic reticulum?

Endoplasmic reticulum. The endoplasmic reticulum (ER) is a type of organelle found 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.
