a. myofibrillar network
b. mitochondria
c. sarcoplasmic reticulum
d. intermediate filament network

The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions (Ca2+).

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.
