FLEXION OF THE CROSS BRIDGE
(THE "FLEX" STAGE)
After the cross-bridge
formation, the ADP and Pi are released
from the myosin head. This causes the myosin head
to rotate, and the cross-bridge flexes. This motion
causes the actin filament to slide relative to
the myosin filament. The miniscule movement of
the actin filament relative to the myosin filament
is the essence of muscular contraction.
