Describe the structure (like the axon, myelin sheath etc) and how it helps with the function
Eg- Myelin sheath helps with faster impulses (cuz of saltatory conduction)

Is this correct?
The cell body includes a nucleus, which contains the genetic material of the cell. Dendrites which carry nerve impulses from neighbouring neurons towards the cell body. Axon carries impulses away from the cell body down the neuron; it is covered in a fatty layer of myelin sheath that protects the axon and speeds up electrical transmission. Myelin sheath is segmented by gaps called nodes of Ranvier that speed up transmission by forcing the impulse to 'jump' across the gaps along the axon. At the end of the axon are terminal buttons that communicate with the next neuron in the chain across a gap known as the synapse
