there's there's nothing happening intracellularly well I don't think that's correct um and in fact it doesn't look to be the case and so there is some sort of combination because here's the here's the juxtaposition there's a thing called lattice spacing which is there's an optimal distance between that myosin and actin in other words if I was trying to produce a powerful contraction but I was buttered up next to each other I can't actually squeeze that hard because there's nowhere to go if I'm too extended then I actually can't yeah it's the same idea as preload in a heart right which is 100 100 the preload is going to determine stroke volume like everything in coming in right so this spacing if you're going to start adding contractile units one way or the other you have to preserve spacing somehow
