How does muscles get bigger with resistance training?   atrophy occurs  myopathy occurs  muscle cells grow muscle cells divide

Why does continuouns calcium release within a muscle fiber cause greater tension? Acticates more calcium pump  Activates myofibrils continuously  Increase action potential frequency  Lengthens sarcomere

Which of the following muscle types and characteristic is correctly matched? Group of answer choices Cardiac muscle : dense body anchoring proteins Skeletal muscle : varicosity at neuromuscular junctions Smooth muscle : Calcium-calmodulin regulation of myosin light chain kinase Cardiac muscle : calcium only from the sarcoplasmic reticulum

How is the list below to be properly put in order to describe a muscular contraction? 1. Calcium causes exocytotic release of Acetylcholine into the synaptic gap; all this happens at an area called the neuromuscular junction2. ATP is consumed which allows myosin to "pivot" the myosin head, which pulls actin toward it.3. This process is repeated multiple times and is called the "sliding filament theory".4. Myosin filaments perform "crossbridging".5. Calcium is released and circulated throughout the muscle cell6. The brain predicts the action necessary and decides which muscles and how many "motor units" are needed to perform that action.7. Tropomyosin moves to reveal the active site of the F-Actin strand8. Upon reception of a calcium ion, the Troponin complex becomes activated9. Proteins embedded in the Sarcolemma receive enough of the ACH neurotransmitter to generate an electrical impulse.10. The electrical impulse is perpetuated throughout the muscle fiber.11. A nervouse impulse is…
