Document Summary

Form exercise- can improve signaling: by more ach receptors, more ach release more to bind to receptors. Excitation contraction coupling twitch contractions, length-tension relationship, fiber types, and recruitment. In order for the myosin head to separate from actin, it needs another atp: causes the myosin to detach from the actin and then go through. Atp hydrolysis and now the head can go to the high energy position: atp has to bind to separate actin from myosin, and then needs to. Brain sends the signal down the cns to spinal chord. Alpha motor neuron travels down the influx of calcium into the neuron and jumps along the neuron through myelin sheath. That depolarization that happens due to influx of calcium that depolarization signals. Ach release signals those vesicles to move from the inside of the neuron and bind to the neuron and release into the synaptic cleft.
