What are ER in muscle called?

What are ER in muscle called?

Skeletal muscle has a specialized form of ER known as sarcoplasmic reticulum (SR). The SR is a storage depot for calcium and regulates its release during myofibrillar contraction; hence, the SR has a critical role in muscle contraction and the maintenance of muscle homeostasis.

What do you mean by endoplasmic reticulum?

The endoplasmic reticulum is a tubular network of membranes found within the cytoplasm of the eukaryotic cell.

What is the endoplasmic reticulum structure?

The general structure of the endoplasmic reticulum is a network of membranes called cisternae. These sac-like structures are held together by the cytoskeleton. The phospholipid membrane encloses the cisternal space (or lumen), which is continuous with the perinuclear space but separate from the cytosol.

What are the 2 types of endoplasmic reticulum?

The ER can be classified in two functionally distinct forms: smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER).

Is a part of the Golgi network?

The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.

What does Golgi look like?

The Golgi apparatus (GA), also called Golgi body or Golgi complex and found universally in both plant and animal cells, is typically comprised of a series of five to eight cup-shaped, membrane-covered sacs called cisternae that look something like a stack of deflated balloons.

What is inside of the nucleolus?

What does the nucleolus contain? The nucleolus contains DNA, RNA and proteins. It is a ribosome factory. Cells from other species often have multiple nucleoli.

What are the important parts of nucleus?

Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components. All of these components work together in order for the nucleus to accomplish all of its functions.
