Sliding filament theory is a model used to explain the mechanism by which muscles contract. The contraction of skeletal muscle, which is what makes movement possible, occurs in three ways.
Some of this calcium attaches to troponin which causes a change in the muscle cell that moves tropomyosin out of the way so the cross bridges can attach and produce muscle contraction. In summary the sliding filament theory of muscle contraction can be broken down into four distinct stages, these are;n order for a skeletal muscle contraction to occur; 1. There must be a neural stimulus. 2. There must be calcium in the muscle cells. 3. ATP must be available for energy. So, a few things can stop a contraction; 1.
