Which part of the nervous system consists of the brain and spinal cord?

The correct answer is the Central Nervous System, which is composed of the brain and the spinal cord. This system serves as the primary control center for the entire nervous system, processing information and coordinating responses throughout the body.

The brain is responsible for higher-level functions such as thought, memory, emotion, and motor control, while the spinal cord acts as a crucial communication pathway transmitting signals between the brain and the rest of the body. Together, they facilitate complex interactions with the environment and regulate bodily functions.

Understanding the structure and function of the Central Nervous System is fundamental in psychology, as it helps to explain how we think, feel, and behave. This distinction is particularly important when differentiating it from other parts of the nervous system, such as the Peripheral Nervous System, which connects the Central Nervous System to limbs and organs, and the Autonomic Nervous System, which regulates involuntary body functions.
