Which of the following is the correct sequence of events for muscle contractions?a) motor neuron action potential, meurotransmit
alexandr402 [8]

The answer is; A

When an impulse from the motor neuron reached the neuromuscular junction,  the voltage-dependent calcium channels are activated and the neurotransmitter released from the presynaptic cleft. When the neurotransmitter binds to their receptors on the sarcolemma, the muscle fibers become depolarised; the calcium is released from their vesicles. The Ca2+ ions are important in the power stroke because they bind to troponin. Upon binding calcium, troponin moves tropomyosin away from the myosin-binding sites on actin. Powered by the energy from ATP molecule,  the myosin is able to bind on the actin and slides over the actin filament.
