State
What distinguishes a hormone from a neurotransmitter is release site and distance, not identity — a neurotransmitter acts locally at a synapse, a hormone travels through blood to targets.

Norepinephrine released at a synapse acts within microns; released into blood, the same molecule reaches organs body-wide.
Watch for
"Hormones and neurotransmitters are entirely different," per Bio 2927, mistakes a role split for chemical split.
