Answer:
Excitation-contraction coupling refers to the events that link the action potentials on the sarcolemma to activation of the <u>Ca+ channels </u> . It begins with the arrival of the <u>action potential</u> at the neuromuscular junction.
Explanation:
The action potential travels from the neuron and it is transmitted to the muscle through the neuromuscular junction, which is the place where the neuron and the muscle join. Once that the action potential is in the muscle this will open Ca+ channels in order to let the Ca+ enter the muscle fiber and produce the contraction in the sarcomere.
