Memory Aid: Remembering the Reflex Arc Pathway

Use "SRRMME" to recall the correct sequence:

  • SStimulus detected (e.g. heat from a pan)
  • RReceptor responds and generates an impulse
  • RRelay neurone in the spinal cord connects the pathways
  • MMotor neurone carries the signal to the effector
  • MMuscle (effector) contracts
  • EEffect — you pull away from the pain before you consciously feel it

Sentence to help: "Smelling Raspberries Requires More Mental Effort"

Key distinction: The relay neurone is inside the spinal cord — this is what makes the reflex fast. The impulse never needs to travel all the way to the brain before the response happens.

Quick Recall Flashcards

What is the reflex arc pathway?
Stimulus → Receptor → Sensory neurone → Relay neurone (in spinal cord) → Motor neurone → Effector → Response.
What is a reflex action?
A reflex is a rapid, automatic response to a stimulus that does not involve conscious thought. Reflexes protect the body from harm.
