シナリオ
The diagram traces the sequence of events at the neuromuscular junction when a nerve impulse arrives, leading to muscle fiber contraction. It includes ACh release, end-plate potential generation, threshold decision, action potential propagation, calcium-mediated excitation-contraction coupling, and relaxation.
この図に含まれるもの
図の背後にある意思決定を読み解く。
01
End-plate potential (EPP) reaches threshold to trigger muscle action potential
02
Insufficient depolarization leads to no response
Ideal for teaching the all-or-none principle in muscle physiology and the steps of excitation-contraction coupling.
