What are neural 'cables' containing many axons that connect the central nervous system with muscles, glands, and sense organs?

What are neural 'cables' containing many axons that connect the central nervous system with muscles, glands, and sense organs?

• A. Nerves
• B. Neurons
• C. Synapses
• D. Brain

Answer: (A)

Bundles of axons wrapped in connective tissue that carry signals between the brain/spinal cord and the rest of the body are nerves. They form the peripheral nervous system and act like cables, delivering motor commands from the CNS to muscles and glands and carrying sensory information from sense organs back to the CNS. Neurons are the individual nerve cells, not cables. Synapses are junctions where neurons communicate with one another, and the brain is an organ within the central nervous system, not a peripheral nerve. So the described structure is nerves.
