Answer:
At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body. It does this by extracting information from the environment using sensory receptors. This sensory input is sent to the central nervous system, which determines an appropriate response.
Explanation: The nervous system is involved in receiving information about the environment around us (sensory functions, sensation) and generating responses to that information (motor functions, responses) and coordinating the two (integration).
In the ways drugs and supplements are the same are they both have an effect of the body's nervous system and both are psychoactive substances. In the ways they are different, drugs are often used for overcoming a illness while supplements are not necessary and are optional. Hope I helped!
