The Information Highway Copyright Houghton Mifflin Harcourt Publishing Company The nervous system is made of tiny structures called nerve cells. Chains of long nerve cells make up nerves. Nerves carry information to and from the brain, which processes information. brain The spinal cord, a rope-like bundle of nerve tissue, is the main pathway for information travelling to and from the brain.
