Nerve

• A nerve consists of bundled axons located outside the Central Nervous System (CNS).
• Nerves are part of the Peripheral Nervous System (PNS).

Tract

• A tract consists of bundled axons located inside the Central Nervous System (CNS).

Ganglion

• Ganglia are part of the Peripheral Nervous System (PNS).

Nuclei
