Answer 1

-Are always excitatory

-Produce end-plate potentials that almost always bring the postsynaptic muscle cell to threshold

-Almost always produce muscle
contractions when the synapse is active

-Are always excitatory and produce end-plate potentials that almost always bring the postsynaptic muscle cell to threshold

-Produce end-plate potentials that almost always bring the postsynaptic muscle cell to threshold and almost always produce muscle contractions when the synapse is active
