Does the Central Nervous System consist of two joined organs: the brain and the spinal cord?

The statement is true because the Central Nervous System (CNS) is indeed composed of two primary components: the brain and the spinal cord. The brain serves as the control center of the body, processing sensory information, coordinating movements, and facilitating cognitive functions. The spinal cord acts as a critical communication pathway, relaying signals between the brain and the rest of the body. Together, these two structures work in tandem to enable the nervous system to function effectively. This definition captures the comprehensive role of the CNS in the overall physiology of the body.

Understanding this framework is crucial in many fields, including medicine and emergency response, as it informs how injuries or conditions affecting either the brain or spinal cord can have widespread implications for bodily functions. The other choices do not accurately represent the composition of the Central Nervous System, as they either suggest the presence of only one of the two organs or incorrectly state its structure.
