Which term refers to a collection of cell bodies outside the CNS?

• A. Nerves
• B. Ganglia
• C. Neurons
• D. Axons

Answer: (B)

A ganglion is a collection of neuron cell bodies located outside the central nervous system. In the peripheral nervous system, these clusters serve as relay points for sensory information or as part of autonomic pathways, helping organize how signals travel to and from the CNS. Nerves are bundles of axons, not cell bodies, so they carry impulses but don’t describe a cluster of neuron somas. Neurons are the cells themselves, which may have their bodies in the CNS or PNS. Axons are the long fibers that transmit signals away from the neuron, not groups of cell bodies.
