Question

information is transmitted along the axon:
by glial cells.
at the speed of light, or 186,000 miles per second.
in the form of a brief electrical impulse.
by chemical substances called neurotransmitters.

Explanation:

Glial cells support neurons but don't transmit axon information. Axon signals are electrical impulses (action potentials) that travel much slower than light; neurotransmitters carry signals between neurons at synapses, not along the axon itself.

Answer:

○ in the form of a brief electrical impulse.
