Verified step by step guidance

Step 1: Begin by understanding the spinal cord's role in the central nervous system (CNS). The CNS consists of the brain and spinal cord, which work together to process and transmit information throughout the body.

Step 2: Recognize that the spinal cord acts as a communication highway. It transmits sensory information from the body to the brain and motor commands from the brain to the body.

Step 3: Clarify that the spinal cord is not involved in filtering waste products from the blood. This function is performed by the kidneys, not the CNS.

Step 4: Note that while the spinal cord plays a role in controlling voluntary muscle movements, it is not limited to this function. It also facilitates reflex actions and transmits signals for involuntary processes.

Step 5: Conclude that the primary function of the spinal cord is to transmit nerve signals between the brain and the rest of the body, enabling communication and coordination of bodily functions.
