Nervous system is made up of...

• A. Nerves
• B. Muscles
• C. Glands
• D. Neurones

Answer: (D)

Neurones are the basic building blocks of the nervous system, the specialized nerve cells that transmit electrical impulses and form networks to carry messages around the body. Nerves are bundles of many neurones with connective tissue, so they are part of how the nervous system works but they are not the individual cells that make up the system. Muscles and glands are effectors that respond to nerve signals, not components of the nervous tissue itself. So neurones is the best answer.
