Model Answer
(i) Dendrite
Function: It receives information/nerve impulses from the environment or other neurons and transmits them toward the cell body.
(ii) Axon terminal (nerve ending)
Function: At the end of the axon, the electrical impulse triggers release of chemicals that cross the synapse and pass the impulse to the next neuron or effector (muscle/gland).

Explanation
- The examiner expects the correct name and a clear one-line function for each part — that's 1 mark per part.
- Key terms to use: receives impulse / chemical reaction / electrical impulse / synapse / axon terminal.
- Avoid confusing dendrite (receiving end) with axon (conducting end). The dendrite picks up signals; the axon terminal releases chemicals across the synapse to pass the signal onward.
