- Reflex arcs are fast responses to protect the body
- Does not involve the brain as this increases the reaction time
- Involuntary action
EG.
Stimulus --> Hot object
Receptor --> Heat sensor in the skin
Impulse travels to the spinal chord along the sensory neuron
Impulse traveled from the spinal chord to the relay neuron
Then to the motor neuron which carries the impulse to the muscle, making it move in response
