D)Glial cell

Question

Quizplus · Accepted Answer

The axon is a long, slender projection of a neuron that carries nerve impulses away from the cell body toward the axon terminals, where they can then be transmitted to other neurons or cells. This makes the axon especially important for carrying messages received by the dendrites to other neurons. Neurotransmitters are chemicals that are released by neurons to transmit signals across synapses, while synapses are the small gaps between neurons where neurotransmitters are released and signals are transmitted. Glial cells are non-neuronal cells that provide support and insulation for neurons, but they do not directly transmit nerve impulses.
