Quizplus · Accepted Answer

A simple nervous system requires three components - sensory information, an integrating center, and effectors. The sensory information is received by the integrating center, which processes the information and sends a response to the effectors, which carry out the response. This system allows for the organism to respond to external stimuli and maintain homeostasis. Chemical senses and vision may or may not be present in a simple nervous system, but they are not required for the system to function. Information flow can occur in both directions in a simple nervous system.
