| | *If patient small with small muscle mass to begin with, total ck may not be elevated- so better to use CK index- is ratio of CKMB/ total CK. Elevated if > 3- 5%. |

| -during contraction of muscle- thick filaments of myosin slide past thin filaments of actin by calcium mediated atp dependent contraction. Released calcium binds to troponin C, T, and I, which regulate muscle contraction. | |
