The sliding filament theory of muscle contraction
:
If you're curious:
Orangeish golf-club looking thing at the top: myosin
Blue thread-like thing: tropomyosin
Orange balls inside the tropomyosin rails: actin
Pink lumps on the tropomyosin rails: troponin
Little yellow ball that binds to the troponin: Ca+
Small green lump on the myosin head: ATP (then released as ADP + Pi)
Grey sphere: Mg+
