Depolarization of dendritic membrane produces a graded synaptic potential, not an action potential, because
a. the depolarization isn't sufficiently strong
b. there aren't enough ligand?gated ion channels
c. there are no voltage-gated ion channels in dendrites, so depolarization can only spread by local current flow
