In neurons without axons, conduction occurs entirely in the form of

D) saltatory conduction.
E) excitation.

Question

Quizplus · Accepted Answer

Neurons without axons, such as interneurons in the spinal cord, rely on graded, decrementally conducted potentials to transmit information over short distances. These subthreshold changes in membrane potential are not propagated as action potentials and do not exhibit all-or-none behavior. Saltatory conduction and excitation are not relevant in neurons without axons.
