What is the central part of the nervous system comprising the brain and spinal cord called?

The central part of the nervous system is referred to as the Central Nervous System (CNS), which comprises the brain and spinal cord. The brain serves as the control center for processing information and coordinating responses while the spinal cord acts as a communication pathway between the brain and the rest of the body. This system is critical for regulating bodily functions, sensory processing, and motor control.

In contrast, the Peripheral Nervous System consists of all the nerves that branch out from the CNS and extend to other parts of the body. The Autonomic Nervous System is a component of the Peripheral Nervous System focused on involuntary control of bodily functions, such as heart rate and digestion. Lastly, the Somatic Nervous System, also part of the Peripheral Nervous System, is responsible for voluntary control of body movements through skeletal muscles. Understanding the distinctions among these systems helps clarify the role of the Central Nervous System as the primary hub of the nervous system.
