Which characteristic would best indicate that a particular synapse is a neuron-to-neuron synapse and not a neuromuscular junction?
A) All impulses reaching the postsynaptic cell are inhibitory.
B) All impulses reaching the postsynaptic cell are excitatory.
C) A single nerve impulse from the presynaptic cell generates an action potential.
D) An action potential results from many small signals received over a long time period.
E) An action potential results from the summation of many small signals received in a short amount of time.
