Muscle movement on the cellular level is initiated by the release of Ca2+ from the terminal cisternae. Terminal cisternae are associated with A. sarcoplasmic reticulum. B. myosin cross-bridges. C. myoglobin. D. canaliculi. E. thin filaments. - correct answer A Muscle fibers store Ca++ in the sarcoplasmic reticulum for release during contraction. The sarcoplasmic reticulum, analogous to the endoplasmic reticulum, runs extensively throughout the fiber so that released Ca++ will come ...
