Nesterboy [21]

Answer:

The primary means for transmitting messages between the brain and the rest of the body is the <u>spinal cord</u>.

Explanation:

The spinal cord is the main pathway of the nervous system. The impulses are transmitted to the brain through bundles of ascending nerve fibers, while the descending fibers transmit impulses in the opposite direction. Signals are transported to and from different parts of the body along the fibers of the pair of spinal nerves, which form intersections with the spinal cord through their dorsal and ventral roots; the sensory and motor fibers converge in the gray matter of the medulla.
