what might be a job of a motor neuron?

• connecting to a muscle and helping you move

• connecting within the brain to help you make a decision

How do nerves trigger muscle contractions?

• By releasing neurotransmitters at neuromuscular junctions.

• By combining actin and myosin into an actinomyosin complex.

• By reversing the post synaptic potential at the neuromuscular junction.

• By releasing Ca2+ ions that are needed for breaking down ATP.
