Nervous System, Neurons and Synapses
Explain basic nervous-system communication from neurons and synapses to coordinated behaviour.
How to study for GCSE Psychology
Confirm the exact board route, connect theories to prescribed studies, apply mechanisms to unfamiliar contexts, evaluate evidence and practise the current paper design.
Core concepts
Concept 1
nervous system
Exam cue: Trace a signal through relevant nervous-system structures and distinguish electrical transmission along a neuron from chemical transmission across a synapse.
Concept 2
neurons
Exam cue: Connect the biological mechanism to a cognition or behaviour without claiming that a single signal explains the whole outcome.
Concept 3
synaptic communication
Exam cue: Use the level of anatomical and process detail required by the current board specification.
Targeted study blocks
Common psychology core
Build the transferable conceptual model
Trace a signal through relevant nervous-system structures and distinguish electrical transmission along a neuron from chemical transmission across a synapse.
Evidence and application
Connect claims to method, findings and context
Connect the biological mechanism to a cognition or behaviour without claiming that a single signal explains the whole outcome.
Current-route boundary
Apply only the live specification detail
Use the level of anatomical and process detail required by the current board specification.
Risk pitfalls and guardrails
Saying that neurons touch or that all communication is purely electrical.
Guardrail: Do not mix board routes, treat one study as proof, diagnose a person or append evaluation that does not change the answer to the question.
Describing a theory or study without applying, analysing or evaluating it when the command requires more.
Guardrail: Do not mix board routes, treat one study as proof, diagnose a person or append evaluation that does not change the answer to the question.
Importing a named theory, core study, diagnosis rule or paper convention from another specification.
Guardrail: Do not mix board routes, treat one study as proof, diagnose a person or append evaluation that does not change the answer to the question.
Memory anchors
Neuron
A specialised cell that transmits information in the nervous system.
Synapse
A junction across which one neuron influences another, commonly through neurotransmitter release.
Biological chain
Name structure, process and resulting influence on cognition or behaviour.
Nervous System, Neurons and Synapses: evidence check
Connect the biological mechanism to a cognition or behaviour without claiming that a single signal explains the whole outcome.
Nervous System, Neurons and Synapses: route check
Use the level of anatomical and process detail required by the current board specification.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
