The lateral sacs of the sarcoplasmic reticulum are called terminal cisternae. These structures are enlarged regions of the sarcoplasmic reticulum that store calcium ions and play a crucial role in muscle contraction by releasing calcium in response to action potentials. They are typically located adjacent to the T-tubules in muscle fibers.
What else can I help you with?
Why is endoplasmic reticulum nickname ER?
The endoplasmic reticulum is often abbreviated as ER because of its extensive network of membrane-bound tubules and sacs that resemble flattened sacs called cisternae. The abbreviation ER is a shortened version of its full name that makes it easier to refer to and remember.
What is the name of the flattened sacs that make up the endoplasmic reticulum?
The flattened sacs that make up the endoplasmic reticulum are called cisternae. These structures are involved in the synthesis, folding, modification, and transport of proteins and lipids within the cell. The endoplasmic reticulum can be classified into two types: rough ER, which is studded with ribosomes, and smooth ER, which lacks ribosomes.
What organelle consists of a sack of flattened sacs?
The endoplasmic reticulum look like flattened sacs.
What are the stacks of membrane covered sacs that package and transport protein to the outside of the cell called?
The stacks of membrane-covered sacs that package and transport proteins to the outside of the cell are called Golgi apparatus or Golgi bodies. They receive proteins from the endoplasmic reticulum, modify them, and package them into vesicles for transport.
What are the flat disc-shaped sacs involved in transporting substances from the endoplasmic reticulum out of the cell?
The flat disc-shaped sacs involved in transporting substances from the endoplasmic reticulum out of the cell are called Golgi apparatus or Golgi bodies. They receive proteins and other molecules from the ER, modify them, package them into vesicles, and transport them to their final destination within or outside the cell.
What surrounds myofibrils?
The sarcoplasmic reticulum are the membranous interconnecting channels and sacs that surround and run parallel to the myofibrils.

What organelle consists of a sack of flattened sacs?
The endoplasmic reticulum look like flattened sacs.
What organelle is closely stacked flattened membrane sacs?
The endoplasmic reticulum is the organelle that's looks like a stack of sacs.
What the structure of the rough endoplasmic reticulum?
It contains flattened sacs called cisternae. Ribosomes are attached to outer surface of its membrane. It is specialized to synthesize proteins.
What cell part is a membranous system of flattened sacs and vesicles?
endoplasmic reticulum
Is the endoplasmic reticulum a stack of membranes that packages proteins into sacs called vesicles?
The endoplasmic reticulum is a network of membranes that includes both rough and smooth regions. The rough endoplasmic reticulum, with ribosomes attached to its surface, is involved in protein synthesis and packaging into vesicles for transport.
What are the stacks of membrane covered sacs that package and transport protein to the outside of the cell called?
The stacks of membrane-covered sacs that package and transport proteins to the outside of the cell are called Golgi apparatus or Golgi bodies. They receive proteins from the endoplasmic reticulum, modify them, and package them into vesicles for transport.
What it endoplasmic reticulum?
A system of parallel flattened membrane-bounded sacs called cisternae. Continuous with the outer membrane of the nuclear envelope. Act as an intracellular transport system.
