Arrange the steps of muscle contraction in the correct order Myosin head forms cross bridge with actin microfilament (thin filament) 1 | ATP binds to myosin - myosin detaches from actin filament 2 E ATP hydrolysis causes conformation change of myosin to the high-energy "cocked" configuration 3 | Phosphate is relased from myosin head 4 E Myosin undergoes a conformational change, sliding the thin filament (Power Stroke) : ADP is released from myosin head

Muscle Action

A change in the body or a bodily organ as a result of its functioning is referred to as an action. Muscle action can be defined as the specific movement of a bodily part generated by the contraction of a muscle. The muscle proteins actin and myosin are the important contractile proteins involved in muscle action. Muscle contraction, in addition to movement, serves several other important functions in the body, including posture, heat generation, and joint stability. Muscle contraction maintains posture, which includes standing and sitting.
