Which part of a neuron is a single elongated process that carries nerve impulses away from the cell body toward the next neuron?
ADendrite
BCyton
CSynapse
DAxon
Answer & Solution
Correct answer: D. Axon
1. The process described is single, long and conducts impulses away from the cell body.
2. Dendrites are many branched projections that conduct impulses toward the cyton, ruling out option A.
3. The cyton is the cell body itself, and a synapse is a junction, ruling out options B and C.
4. The single process carrying impulses away is the axon, option D.
