Components of a Reflex Arc

• What is the correct order of components in a reflex arc?

  Receptor → Sensory neuron → Motor neuron → Effector
• What is the role of the sensory neuron in a reflex arc?

  To carry the impulse from the receptor to the spinal cord
• What is the function of the motor neuron in a reflex arc?

  To carry the impulse from the spinal cord to the effector
• What is the role of the effector in a reflex arc?

  To produce a response to the stimulus
• What is the function of the interneuron in a reflex arc?

  To connect the sensory neuron to the motor neuron in the spinal cord
• Where does a reflex arc usually occur in the body?

  In the spinal cord
• Which part of the reflex arc detects the stimulus?

  Receptor
• What happens when a stimulus is detected in a reflex arc?

  A response is sent to the effector to trigger an action
• What type of response does a reflex arc produce?

  An involuntary, automatic response
• In which part of the nervous system does the reflex arc primarily operate?

  Central nervous system
