The process of muscular contraction occurs over a number of key steps, including: Depolarisation and calcium ion release. Actin and myosin cross-bridge formation. Sliding mechanism of actin and myosin filaments. Sarcomere shortening (muscle contraction)

Action potential generated, which stimulates muscle.

Ca2+ released.

Ca2+ binds to troponin, shifting the actin filaments, which exposes binding sites.

Myosin cross bridges attach & detach, pulling actin filaments toward center (requires ATP)

Muscle contracts
