a stimulus.
interneurons
spinal cord
sensory neurons
motor neurons
What is the next step?
1. Receptor cells detect a stimulus.
2. This information is transformed into an impulse.
3. ______________________________

reflex arc.
An effector carries out a response to prevent injury.
A motor neuron carries a message to an effector.
