What things need to be above the threshold when the impulse reaches the neuromuscular junction?

• ACH

• Synaptic Cleft Gap

• Speed of signal

• Action Potential

If ACH and the Action Potential are above the threshold, what will happen next?

• The muscle contracts

• The nerve impulse will cross the synaptic cleft

• Wave of Contraction
