Sliding Filament Theory 3d Model. I thought the best way to explain this process was by animation. The sliding filament theory.
To get the actin together the myosin has cross bridges which pull them near each other but the actin has proteins tropmyosin and troponin which stop the cross bridges from pulling them together. It is proposed that muscle contracts by the actin and. In other words for a muscle cell to contract the sarcomere must shorten.
The sliding filament theory explains the basis of skeletal muscle contraction and specifically deals with the movement of myosin heads along an actin fiber in the sarcomere.
You will present your model on a segment of the fictitious show csi the science revealed targeted to middle and high school students. Yes it took ages and yes it s not getting best animated short at the oscars but. At first the muscle is relaxed. This model will be manipulated to show the sequence of events that occur during normal shortening of the sarcomere as well as educate your audience on why the muscles can lock up after death.
