In Extrasynaptic Communication, Glial Cells

In extrasynaptic communication, glial cells

A) are the only cells capable of extrasynaptic neurotransmitter release.
B) work in coordination with neurons, with both capable of extrasynaptic neurotransmitter release.
C) provide the physical scaffolding needed for molecules to pass from one neuron to the next.
D) help construct a filter to prevent extrasynaptically released molecules from leaving the brain.
E) reduce the distance that signals can travel, by repackaging any molecules released outside of synapses.
