Final answer:
The central nervous system consists of the brain and spinal cord, which are responsible for coordinating reflexes, regulating homeostasis, and facilitating conscious experiences. The correct answer is 1.
Step-by-step explanation:
The Central Nervous System
The central nervous system is made up of two key components: the brain and the spinal cord. These are the main organs of the nervous system responsible for a wide range of functions, including the coordination of reflexes, regulation of homeostasis, and facilitating conscious experiences.
The Brain
The adult brain can be divided into four major regions: the cerebrum, the diencephalon, the brain stem, and the cerebellum. The cerebrum is further divided into four lobes, each with distinct functions contributing to our complex behaviors and abilities.
The Spinal Cord
The spinal cord is a singular structure running from the base of the brain down through the spinal column. It functions as a pathway for neural activity, carrying signals between the brain and the rest of the body, and is integral in the coordination of reflexes.
Therefore the correct option is 1.
