The human nervous system is comprised of two subsystems known as the ________ and ________.

• A. Central Nervous System, Peripheral Nervous System
• B. Autonomic Nervous System, Somatic Nervous System
• C. Brain and Spinal Cord
• D. Neurons and Glia

Answer: (A)

Two broad parts organize the nervous system: the Central Nervous System, which includes the brain and spinal cord, and the Peripheral Nervous System, which encompasses all neural tissue outside the CNS such as nerves and ganglia. The CNS handles processing, integration, and control, while the PNS transmits sensory information to the CNS and carries motor commands from the CNS to muscles and glands, enabling actions. The other options mix up what the major divisions are: the brain and spinal cord are components of the CNS, not a separate two-part division; neurons and glia are cell types; and the Autonomic and Somatic divisions are functional pathways within the Peripheral Nervous System, not the two overarching subsystems.
