What Is Excitation-Contraction Coupling?

Excitation -contraction co-npling

Excited contraction coupling

Right!
Excitation -contraction co-npling
The coupling process from muscle fiber cell membrane excitement to muscle contraction. It includes the following procedures: Excitation is transmitted from the cell membrane through the "T" tube to the sarcoplasmic reticulum that surrounds myofibrils, causing the sarcoplasmic reticulum to release Ca2 +, so that the myofibrils A and I filaments begin to interact with ATP Break down and cause muscle contraction.
