A: When heart muscle recovers from damage, it forms scar tissue, meaning that its usefulness for cardiac functions afterward is compromised. Heart muscles differ from skeletal muscles, which may be tetanized or contracted for prolonged periods to allow for lifting or other sustained actions. Tetanization would make the heart ineffective as a pump.Quote from: shockley1 (5 years ago)A C T I V I T Y 3(Examining the Effect of Vagus Nerve Stimulation)5. Cardiac Muscle Lacks Troponin.
