💡 Exam Tips: Nervous System
Name the neurone type at each stage: Never just say "a nerve carries the message." Identify whether you mean a sensory, relay, or motor neurone at each point in the pathway.
Synapse questions need four steps: (1) impulse arrives at pre-synaptic membrane, (2) neurotransmitter released from vesicles, (3) neurotransmitter diffuses and binds to receptors, (4) new electrical impulse generated. Missing any step loses a mark.
Accommodation table — learn the near column: If you know what happens for near objects (ciliary muscles contract, ligaments loosen, lens thick/curved), the distant column is the opposite. Learn one, get both.
Comparison questions need both sides: "Nervous system is fast" earns half the marks — add "whereas the hormonal system is slower" for full credit.
Brain regions — function first: If asked "state the function of the cerebellum", write "coordinates muscle movement and maintains balance" — don't describe its location.
RPA7 — control variables matter: State that temperature, distraction, caffeine, and practice must be controlled. Repeating and averaging reduces the effect of anomalies.
