Question

At a neuromuscular junction Group of answer choices neurotransmitters are released. actin and myosin filaments slide past one another. intercalated discs are synthesized. troponin and tropomyosin exchange places.

Answer 1

Neurotransmitters are released

Step-by-step explanation:

At a neuromuscular junction, action potential that arrives there causes the release of the acetylcholine into the synapse. This then binds to the receptors that span across the surface of the motor end plate triggering muscle contraction with the release of calcium.

It acts as a transmission passageway for action potential between the end of a motor nerve and a muscle.
