Question

what is the function of the spinal cord?
to relay information from the brain to the rest of the body and from the rest of the body to the brain
to protect the spine from injury
to relay information from the brain to the rest of the body only
to relay information from the rest of the body to the brain only

Explanation:

The spinal cord is a crucial part of the central nervous system. It acts as a communication pathway. It transmits signals (information) from the brain to the rest of the body (motor signals) and also sends sensory information from the rest of the body back to the brain. The spine (vertebrae) protects the spinal cord, not the other way around. Options that mention only one - way relay (either brain to body only or body to brain only) are incorrect as it is a two - way relay.

Answer:

To relay information from the brain to the rest of the body and from the rest of the body to the brain.
