How do you develop a reflex arc?
assistant
The development of a reflex arc begins by identifying the stimulus and the appropriate response. Next, the relevant neuron pathways must be connected to sense the stimulus and to generate the response. The neuron pathways may involve sensory neurons from the receptor to the central nervous system, motor neurons from the central nervous system to the effector, and interneurons that connect sensory and motor neurons. Finally, the pathways must be reinforced with practice, so that the proper response is elicited automatically depending on the stimulus encountered.
