Myofilaments are the
three protein filaments of
myofibrils in
muscle cells. The main
proteins involved are myosin, actin, and titin.
Myosin and
actin are...

actin myofilaments along each other. Each
myofibril has a
diameter of
between 1 and 2
micrometres (μm). The
filaments of myofibrils,
myofilaments, consist...

muscle myofilaments of
myosin and
actin slide past each other,
pulling the Z-lines together.
During an
eccentric contraction, the
myofilaments slide past...

thick myofilament made up of
myosin that acts in
