Answer
The correct sequence in a typical reflex arc is:
Receptor, sensory neuron, integration center, motor neuron, effector.
Receptor, sensory neuron, integration center, motor neuron, effector.
Solution
In a typical reflex arc, the correct sequence is:
- Receptor: Detects the stimulus.
- Sensory neuron: Transmits the signal from the receptor to the integration center.
- Integration center: Processes the information and determines the response (usually in the spinal cord).
- Motor neuron: Carries the response signal from the integration center to the effector.
- Effector: Executes the response (e.g., muscle contraction or gland secretion).
Therefore, the correct sequence is:
Receptor, sensory neuron, integration center, motor neuron, effector.

In a typical reflex arc, the sequence starts with the receptor, which detects a stimulus. This is followed by the sensory neuron that transmits the information to the integration center, typically the spinal cord, where the signal is processed. From there, the motor neuron carries the response signal to the effector, which elicits a reaction, such as a muscle contraction.
Reflex arcs are incredibly efficient for rapid responses. This is why you quickly jerk your hand away from a hot surface without having to think about it! Think of reflexes as your nervous system’s way of performing a lightning-fast dance to keep you safe from harm and maintain bodily functions.
