Which part of the nervous system is responsible for the brain and spinal cord?

The central nervous system is responsible for processing and transmitting information throughout the body and is composed of the brain and spinal cord. It serves as the control center for all neural functions, including motor activities, sensory information processing, and higher cognitive functions.

The brain interprets sensory input, makes decisions, and coordinates complex behaviors, while the spinal cord serves as a critical pathway for transmitting signals between the brain and the peripheral body. This system plays a fundamental role in maintaining homeostasis, reflex actions, and voluntary movements. Understanding the function and structure of the central nervous system is crucial for various fields, including medicine, psychology, and law enforcement, as it directly relates to human behavior and responses.
