How does blocking calcium channels cause muscle relaxation?

Question

Quizplus · Accepted Answer

ACh synthesis and release is a cyclical process.The process is stimulated by an influx of calcium into the neuronal endplate.Calcium entry occurs through voltage-regulated N channels.The influx of calcium raises the positive ions inside the cell,causing changes in the presynaptic membrane that result in the release of ACh from its storage vesicle.After ACh is released into the neuromuscular junction,a new vesicle begins to form in the presynaptic neuron.New ACh is synthesized in this vesicle.When the process is complete,the new vesicle filled with ACh buds off,awaiting a signal to release its contents.
