Name the part of a neuron where information from the environment is first received. How is this information then converted and transmitted along the length of the nerve cell to reach the next neuron?

Model Answer
The dendritic tip of a nerve cell first receives information from the environment.
This information sets off a chemical reaction that creates an electrical impulse. The impulse travels from the dendrite → cell body → along the axon to its end. There, it triggers release of chemicals that cross the synapse and start a similar electrical impulse in the dendrite of the next neuron.

Explanation
- Part 1 (1 mark): Name the part — "dendritic tip." Just "dendrite" is also acceptable but "dendritic tip" is the exact textbook term.
- Part 2 (1 mark): Describe the conversion (chemical → electrical impulse) and the pathway (dendrite → cell body → axon → synapse → next neuron). Examiners look for: the word electrical impulse, the correct sequence, and mention of the synapse. Missing the synapse or the chemical-to-electrical conversion will lose marks.
