Collections of neuron cell bodies outside the CNS are called?

• A. Nuclei
• B. Tracts
• C. Ganglia
• D. Fascicle

Answer: (C)

This question tests where neuron cell bodies are located in the nervous system. Collections of neuron cell bodies outside the central nervous system are called ganglia. In contrast, within the CNS these cell bodies form nuclei. The other terms refer to axons rather than cell bodies: tracts are bundles of axons in the CNS, and fascicles are smaller bundles of axons within nerves. So outside the CNS, the correct term for the cell bodies is ganglia.
