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.

Neurotransmitters are released

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.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
