- Reflex arc is the shortest path taken by a nerve impulse from a receptor to an effector.
- It includes five components: receptor, sensory neuron, CNS, motor neuron, and effector.
- The receptor detects the stimulus and sends the impulse to the sensory neuron.
- The CNS processes the impulse and sends it through the motor neuron.
- The effector (muscle or gland) carries out the response.
