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...
- store, the
sarcoplasmic reticulum. The rise in
calcium causes the cell's
myofilaments to
slide past each
other in a
process called excitation-contraction coupling...

myofibrils consisting of long
protein chains of
myofilaments.
There are
three types of
myofilaments: thin, thick, and
elastic that work
together to produce...
- head is the part of the
thick myofilament made up of
myosin that acts in
muscle contraction, by
sliding over thin
myofilaments of actin.
Myosin is the major...

muscle contraction to
release and the body to relax.
Decomposition of the
myofilaments occurs between 48 and 60
hours after the peak of
rigor mortis, which...
- part of the
troponin protein complex,
where it
binds to
actin in thin
myofilaments to hold the actin-tropomyosin
complex in place.
Troponin I

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