Which three main components are involved in the flow of information within the organization of the nervous system?

• A. Cerebrum, cerebellum, and brainstem
• B. Sympathetic, parasympathetic, and enteric divisions
• C. Dendrites, axons, and synapses
• D. Sensory input, integration, and motor output

Answer: (D)

Verified step by step guidance

1. Understand that the nervous system processes information through a sequence of stages that allow it to respond to stimuli effectively.
2. Identify the first component: Sensory input, which involves detecting stimuli from the environment or the body and sending this information to the central nervous system.
3. Recognize the second component: Integration, where the nervous system processes and interprets the sensory information to make decisions or form responses.
4. Note the third component: Motor output, which is the response generated by the nervous system, sending signals to muscles or glands to act accordingly.
5. Conclude that these three components—sensory input, integration, and motor output—represent the fundamental flow of information within the nervous system, distinguishing them from anatomical parts or divisions.
