Which part of the body contains the Central Nervous System?

The Central Nervous System (CNS) is comprised of the brain and spinal cord. This system is responsible for processing and transmitting information throughout the body, enabling various functions including thought, movement, and coordination. The brain acts as the control center, processing sensory information and sending signals to the body, while the spinal cord serves as a major conduit for information traveling between the brain and the rest of the body.

In contrast, the other options do not represent components of the Central Nervous System. The arms and legs are part of the peripheral nervous system, involved in movement and sensation but not in processing information. The heart and lungs are vital organs for circulation and respiration, respectively, and play no role in nerve signal processing. Lastly, the digestive organs are responsible for processing food and nutrients, unrelated to the functioning of the CNS. Understanding the role and components of the CNS highlights its central importance in bodily functions and overall health.
