Detailed explanation-1: -Within the spinal column lies the spinal cord, a vital aspect of the central nervous system (CNS). The three primary roles of the spinal cord are to send motor commands from the brain to the body, send sensory information from the body to the brain, and coordinate reflexes.

Detailed explanation-2: -The brain and spinal cord are your body’s central nervous system. The brain is the command center for your body, and the spinal cord is the pathway for messages sent by the brain to the body and from the body to the brain.

Detailed explanation-3: -By way of the peripheral nervous system (PNS), nerve impulses travel to and from the brain through the spinal cord to a specific location in the body. The PNS is a complex system of nerves that branch off from the spinal nerve roots.

Detailed explanation-4: -Nerves In the Peripheral Nervous System Sensory: Connects the brain and spinal cord to your skin and allow you to feel pain and other sensations. Autonomic: Controls involuntary function (e.g., blood pressure, digestion, heart rate). Motor: Connects the brain and spinal cord to muscles to stimulate movement.

Detailed explanation-5: -The main function of the peripheral nervous system is to connect the central nervous system to the limbs and organs, essentially serving as a relay between the CNS i.e. the brain and spinal cord and the rest of the body.
