(Students must draw a proper labelled diagram showing: dendrites, cell body/nucleus, axon, myelin sheath, and nerve endings.)
Two parts and their functions:
- Dendrites – They receive information (nerve impulses) from the environment or from other neurons and pass it to the cell body.
- Axon – It carries the electrical impulse from the cell body to its end, where the impulse is converted into a chemical signal for transmission to the next neuron.

Explanation
- The diagram carries marks — label at least 4–5 parts clearly (dendrite, cell body, nucleus, axon, nerve endings/synaptic knob).
- For the two functions, examiners look for specific roles: dendrite = receives impulse; axon = transmits impulse away from cell body.
- Avoid vague answers like "it helps in communication" — use precise terms: electrical impulse, chemical signal, synapse.
- You may choose any two labelled parts, but dendrite and axon are the safest choices as their functions are explicitly stated in the textbook.
