Put the following events of excitation-contraction coupling in the order in which they occur.
1) Excitation
2) Sarcomere shortening
3) Generation of muscle tension
4) Neural control
5) Contraction cycle begins
6) Release of calcium ions

Question

Quizplus · Accepted Answer

The correct sequence for excitation-contraction coupling starts with neural control (4), followed by excitation of the muscle fiber (1), then the release of calcium ions (6), which triggers the contraction cycle to begin (5). This leads to sarcomere shortening (2) and ultimately results in the generation of muscle tension (3).
