In the CNS, groups of cell bodies are called ______ and bundles of axons are called _____.

Question

BlackTom AI · Accepted Answer

Consider the fundamental neuroanatomy terminology for the central nervous system (CNS) versus the peripheral nervous system (PNS).
Option 1: 'nuclei; tracts' correctly uses nuclei to describe groups of neuron cell bodies within the CNS and tracts to describe bundles of axons also within the CNS. This aligns with standard anatomical terminology.
Option 2: 'tracts; nuclie' swaps the order and also misspells 'nuclei' as 'nuclie'. In the CNS, tracts are indeed bundles of axons, but they are not described as 'cell bodies'; cell bodies are not grouped by 'tracts'. The misspelling also makes this option incorrect as a factual descriptor.
Option 3: 'ganglia; nerves' uses terms associated with the PNS. Ganglia are clusters of neuronal cell bodies outside the CNS, and nerves are bundles of axons in the PNS. This combination does not match CNS terminology.
Option 4: 'nerves; ganglia' again confuses CNS versus PNS. Nerves are bundles of axons in the PNS, and ganglia are clusters of cell bodies outside the CNS. This pairing is not appropriate for describing CNS structures.
By comparing all options, we see that the CNS-specific pairing is 'nuclei; tracts', while the others mix CNS/PNS terminology or contain errors such as misspelling or wrong anatomical associations.
