Troponin-Tropomyosin Complex

A regulatory protein complex in muscle cells that controls the interaction of actin and myosin, essential for muscle contraction.

Myosin Heads

The part of the myosin protein that binds to actin filaments and performs the power stroke to cause muscle contraction.

Cross-Bridges

The connections formed between actin and myosin filaments in muscle fibers during contraction.

Actin Myofilaments

Thin filaments within muscle cells that, along with myosin, contribute to muscle contraction and relaxation.
