QUESTION 14 Excitation-contraction coupling refers to OA. The action potential of a neuron triggering the release of neurotransmitters from synaptic vesicles. O B. The relationship between length of the sarcomere and the tension generated. OC. The sliding of thick and thin filaments past one another. OD. The relationship between excitation at the sarcolemma and release of calcium ions from the terminal cisternae of the sarcoplasmic reticulum.
