The sequence of events that links the action potential to the contractionis referred to as excitation-contraction coupling. -How does that action potential down the motor neuron result in contraction of the muscles? -Describe the series of events of events that occurs in excitation-contraction coupling. Begin with acetylcholine being released at the axon terminal of the motor neuron and end with the muscle fibers relaxing after contraction.Some key terms you should include in your post: -sarcoplasmic reticulum -Ca++ pumping -Impulse -T tubule Health Science Science Nursing PHYSIOLOGY SCI221-7 Share QuestionEmailCopy link Comments (0)
