Question

the nervous system is responsible for the bodys muscle movement, coordination and control. it is divided into the central nervous system and the peripheral nervous system. the central nervous system is composed of the brain and the spinal cord. the brain is the major control center. it gives us the power to think and move, write, solve problems and imagine. it interprets all the information sent to it from outside and inside the body, and it controls our body temperature, heart rate and breathing. the spinal cord is a bundle of nerve fibers that runs along the back and connects the brain to all of the other nerves in the body. these nerves that extend throughout the body are called the peripheral nervous system. they transfer messages to and from the brain via the spinal cord.
which of the following best describes how the spinal cord and the brain work together?
choose one option
a messages travel to and from the brain to other parts of the body through the spinal cord.
b the spinal cord controls the bodys movement, and the brain controls coordination.
c the spinal cord sends messages to the brain, telling it what functions to perform.
d the spinal cord is a bone in the back that supports your skull, which houses the brain.

Explanation:

The text states the spinal cord connects the brain to other nerves, and peripheral nerves transfer messages to/from the brain via the spinal cord. Option A directly reflects this collaboration. Option B misassigns functions (brain controls movement/thinking), C reverses message direction, D incorrectly calls the spinal cord a bone.

Answer:

A. Messages travel to and from the brain to other parts of the body through the spinal cord.
