Quizplus · Accepted Answer

Glutamate opening sodium gates is a direct and rapid process, which is the hallmark of ionotropic effects. Metabotropic effects, on the other hand, involve slower processes mediated by G protein-coupled receptors, and modulatory effects involve the altering of the strength of an existing synapse. Orthodromic refers to the normal direction of impulse transmission down an axon.
