WebMuscles cause movement by contracting. During muscle contraction, sarcomeres within myofibrils shorten as the Z discs are pulled closer together. This is known as the sliding filament model of muscle contraction and occurs via the following process: An action potential arrives at the neuromuscular junction. Calcium ions are released from the ... WebTo enable a muscle contraction, tropomyosin must change conformation, uncovering the myosin-binding site on an actin molecule and allowing cross-bridge formation. This can only happen in the presence of calcium, …
