What is the difference between treppe and tetany? Mark ALL that apply. there is no summation in tetany there is no summation in treppe the contractions successively increase giving a "staircase" image treppe goes away after muscle is fully warmed up treppe is caused by gradual warming of an unstimulated muscle thus increasing diffusion of ians and protein movement needed to cause contractions.

The muscle relaxes if no new nerve signal arrives. However the neurotransmitter from the previous stimulation is still present in the synapse The activity of helps to remove this neurotransmitter. myosin action potential tropomyosin acetylcholinesterase
After death, a person no longer makes ATP, so calcium stored in the sarcoplasmic reticulum diffuses down its concentration gradient into the muscle cytoplasm. This result is rigor mortis----an unbreakable state of muscle contraction that stiffens the body for a few days until muscles begin to decay. Explain why this contraction occurs.
After death, calcium pumps no longer function and the calcium ion concentration of muscle fiber cytoplasm increases. The result is rigor mortis a state or postmortem muscle contraction. Explain why this contraction occurs and why it ends only when myosin heads begin to break down.
Figure 38.37 Which of the following statements about muscle contraction is true? The power stroke occurs when ATP is hydrolyzed to ADP and phosphate. The power stroke occurs when ADP and phosphate dissociate from the myosin head. The power stroke occurs when ADP and phosphate dissociate from the actin active site. The power stroke occurs when Ca2+ binds the calcium head.
