Signaling in Muscle Contraction

Calcium triggers contraction in striated muscle. (A) Actomyosin in striated muscle.(1) Striated muscle in the relaxed state has tropomyosin covering myosin-binding sites on actin.(2) Calcium binds to troponin C, which induces a conformational change in the troponin complex.This causes tropomyosin to move deeper into the actin groove, revealing the myosin-binding sites.

random cracking. A contraction joint may be designed as a complete break in the structure, each cast butting against the previous one. If more structural stability is needed between sections the reinforcement may be continued across the joint to restrict its opening. Forming grooves in the concrete surface - top, bottom or both - makes another
