What are nerves?

• A. Bundles of nerve fibers
• B. Neurons
• C. Synapses
• D. Collections of glial cells

Answer: (A)

Nerves are bundles of nerve fibers (axons) wrapped together in connective tissue, forming part of the peripheral nervous system. These bundles carry both sensory information from the body to the brain and motor commands from the brain to muscles, often containing a mix of different fiber types. An individual neuron is a single nerve cell, not a whole nerve. Synapses are the junctions where signals pass between neurons, not the bundles themselves. Glial cells are support cells for neurons, not the bundled structures that make up a nerve.
