Answers
Answer:
The sarcotubular system is a network of membranes that is found in striated muscle fibers, and includes two components consisting of transverse tubules and cisternal formations.

Answer:
A network of membranes found in striated muscle fibres.
Explanation:
Transverse tubules and cisternal formations make up the two parts of the sarcotubular system, a network of membranes found in striated muscle fibres.
In the sarcoplasm between the myofibrils of the frog skeletal muscle cell is a clearly defined and meticulously structured system of tubular components.
The sarcotubular system is the name of the sarcoplasmic component.
The main intracellular calcium store in striated muscle is the sarcoplasmic reticulum (SR), which also has a significant impact on the control of excitation-contraction coupling (ECC) and intracellular calcium concentrations during contraction and relaxation.
The components of the sarcotubular system, which include triads (*), Z-tubules (ZT), longitudinal tubules (LT), and fenestrated collar, are once more shown in a tangential section of a shortened fibre
