Verified step by step guidance

Understand that a reflex arc is a neural pathway that controls a reflex action. It involves several components that work in a specific sequence to produce a response.

Identify the first component: The 'Receptor' is the structure that detects the stimulus. It initiates the reflex by sending signals to the next component.

Recognize the second component: The 'Sensory Neuron' carries the signal from the receptor to the central nervous system (CNS).

Determine the third component: The 'Integration Center' is located within the CNS. It processes the information and determines the appropriate response.

Identify the final components: The 'Motor Neuron' carries the signal from the integration center to the 'Effector', which is the muscle or gland that executes the response.
