Muscular system

The muscular system is responsible for the movement of the human body. There are about 700 muscles that are attached to the bones of our body.

How skeletal muscle contracts

Skeletal muscles contracts by The myosin filaments having heads (they form cross-bridges when they're attached to biding sets on acting filaments). Then, the ATP binds the myosin heads and causes them to break the cross-bridges by detaching from the binding sites. Finally, the ATP is broken down to ADP and phosphate , causing the myosin heads to change angle.
