At the neuromuscular junction, the arrival of acetylcholine on the muscle most immediately causes _____. view available hint(s) at the neuromuscular junction, the arrival of acetylcholine on the muscle most immediately causes _____. a graded hyperpolarization the release of second messengers, such as camp a single action potential an inhibitory postsynaptic potential a graded depolarization

Answer 1

At the neuromuscular junction, the arrival of acetycholine on the muscle most immediately causes a graded depolarization. Graded potentials are the changes in membrane potential that vary in size, as opposed to being all or none. Graded potential can be depolarizing or hyperpolarizing depending on the stimulus. Action potentials on the other hand always lead to depolarization of membrane and reversal of the membrane potential.
