The most appropriate statement that is explaining the effect and cause during muscle contraction is.
“The release of calcium ions causes myosin and actin to attach to each other.”
The activation of muscles helps in the generation of muscles that send out the signals to the neurons.
Then there is the process of muscles contraction which binds the cell.
