Question

Quizplus · Accepted Answer

A basic nervous system includes sensory information, an integrating center, and effectors. This is because there needs to be a way to sense stimuli, process and integrate that information, and then respond to it. Chemical senses, mechanoreception, and vision may be components of a nervous system, but they are not required for it to be considered basic. There is no minimum number of effector neurons required for a nervous system to be basic, and information flow can go in both directions depending on the specific pathways and reflexes involved.
