So we're actually focused on skeletal muscles.
This is what we wanted to get to, but we're going to go even within the muscle cell to see, understand how all the myosin and the actin filaments fit into that muscle cell.
This is your next Z-band.
The calcium floods all of these myofibrils.
So it has many more heads than what I'm drawing, but this just gives you an idea of what's happening.
I read one-- I think it was 30 or so nucleuses per millimeter of muscle tissue is what the average is.
It's the ultimate pec lovers dream come true.
So the myosin is held in place by titin.
