The path of movement of electrical impulse starts from the dendrites. Then it passes through cell body, axon, axon terminal and to the dendrites of another neuron through the synapse. Myelin sheath acts as insulator, Nodes of ranvier are small gaps in axons which facilitate the impulse transfer.
The only thing not balanced is the Oxygen gas (O2). Since you have carbon dioxide, you have 2 oxygens there and 2 oxygens since there are 2 waters on the right. So you have 2 on the left and 4 on the right. To fix it, put a 2 on front of the O2 on the left and that should balance it.
