Myosin : Thick Filament
Actin: Thin Filament
There's a space between the Z line which is called the Sacromere.
Calcium ions come into the Sarcomere and cause the myosin and actin filaments to attach to each other
This is a Actin filament (zoomed in) which is called trypomyosin. The beads are tropomyosin that block the myosin from binding
This is a closer look of the acting filament(red) with the myosin(blue)
