In the reflex arc, which order are the quick response signals in? |
Sensory neurone ➡ relay neurone ➡ motor neurone |
S____ r _____ m_______ neurone |
|
|
Define ' reflex arc ' |
A reflex arc is a nerve pathway which makes an automatic, innate response. |
Keywords - nerve pathway, innate, automatic |
|
|
Stages of the reflex arc are: |
🔹stimulus (eg.heat) 🔹pain receptor is stimulated 🔹signal sent along sensory neuron 🔹signal passed along relay neuron (a message is sent to the brain) 🔹signal sent along motor neuron 🔹effector muscle contacts (limb is moved away💪) this is the response. |
Stimulus ➡ receptor ➡ effector ➡ response |
|
