Which system carries information from receptors to the central nervous system?

• A. Sensory nervous system
• B. Motor nervous system
• C. Autonomic nervous system
• D. Central nervous system

Answer: (A)

The main idea is how information travels from sensing structures toward the brain and spinal cord. The sensory nervous system is the pathway that carries signals from receptors to the central nervous system. When a receptor detects a stimulus, it generates impulses that travel through sensory neurons toward the CNS (the afferent pathways). These signals eventually reach the brain and spinal cord for processing. In contrast, the motor nervous system sends commands from the CNS to muscles or glands (efferent pathways), not information from receptors to the CNS. The autonomic system deals with involuntary regulation of internal organs and includes sensory and motor components, but its overall role isn’t the general incoming transmission from receptors to the CNS. The central nervous system itself is where processing occurs, not the transmission route from receptors.
