Master Reflexes fast ⚡ – clear explanations, OCR-aligned.
You’ll cover
• What reflex actions are and why they are rapid, automatic responses to stimuli.
• The structure of a typical reflex arc and the roles of receptors, sensory neurones, relay neurones and motor neurones.
• Why reflex pathways bypass higher brain processing to produce very fast responses.
• The difference between cranial reflexes and spinal reflexes.
• The biological importance of reflexes for protection, posture and survival.
What’s included
• Labelled diagram showing the structure of a typical reflex arc, including receptor, sensory neurone, relay neurone, motor neurone and effector.
• Illustration of the spinal cord showing grey matter, white matter and the position of neurones within the reflex pathway.
• Explanation of how the nervous pathway in a reflex arc minimises response time.
• Table summarising common reflex examples, including corneal blinking reflex, optical blinking reflex and the knee-jerk reflex.
• Clear breakdown of reflex coordination sites, main stimuli, effectors and survival value.
