GCSE Human Nervous System

This detailed revision resource covers the Human Nervous System topic from the AQA GCSE Combined Science Biology specification. Designed as a comprehension‑style activity, it provides clear, structured revision notes written in accessible, student‑friendly language, followed by 15 exam‑style questions with a separate mark scheme available.

Topics covered:

Homeostasis and control systems, including stimuli, receptors, coordination centres, effectors, and negative feedback

The pathway from stimulus to response (stimulus → receptor → sensory neurone → CNS → motor neurone → effector)
The reaction time required practical, including method, variables, safety and evaluation
Reflexes and the reflex arc, including the role of relay neurones and the spinal cord
Synapses and neurotransmitter action during impulse transmission

A comprehensive Word document containing detailed revision notes and a set of structured comprehension questions
A glossary of key terms (e.g., homeostasis, neurone, CNS, synapse, reflex) to support accessibility for VI learners
A separate Word document mark scheme with full model answers and mark allocations

Perfect for:

GCSE Combined Science Biology (suitable for both Foundation and Higher students)
Independent revision, homework, or catch‑up work
Classroom teaching, intervention groups, or pre‑assessment preparation
VI‑friendly delivery: clear structure, accessible language, no unnecessary diagrams, and screen‑reader‑friendly formatting
