What is the term for bundles of axons in the peripheral nervous system?

• A. Nerves
• B. Tracts
• C. Ganglia
• D. Cortex

Answer: (A)

In the peripheral nervous system, axons are grouped into organized bundles called nerves. These nerves carry sensory and motor information to and from the body's muscles and organs, and they’re wrapped in connective tissues for protection. In the central nervous system, the same idea of axon bundles exists, but the term used is tracts. A ganglion is a cluster of neuron cell bodies, not axon bundles, and the cortex refers to the outer layer of the brain. So the term for bundles of axons in the peripheral nervous system is nerves.
