Detailed explanation-1: -The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord. The spinal cord begins at the bottom of the brain stem (at the area called the medulla oblongata) and ends in the lower back, as it tapers to form a cone called the conus medullaris.

Detailed explanation-3: -The autonomic nervous system is regulated by integrated reflexes through the brainstem to the spinal cord and organs.
Detailed explanation-4: -The spinal nerves emanate from the spinal cord as pairs of nerves composed of both sensory and motor fibers that function as the intermediary between the central nervous system (CNS) and the periphery.
