Which term is described as the portion of the nervous system associated with processing information and containing many neuronal cell bodies and dendrites?

• A. White matter
• B. Brainstem
• C. Grey matter
• D. Nerve fibers

Answer: (C)

Processing information happens in tissue rich in neuron cell bodies and dendrites, where synaptic connections form and signals are integrated. This tissue is grey matter, found in the cerebral cortex and deep brain nuclei, and it appears grey because neuron cell bodies stain darkly. In contrast, white matter is made mainly of myelinated axons that transmit signals between regions, so it’s less about processing and more about communication. The brainstem is a region containing both grey and white matter, and nerve fibers refer to axons in white matter. So the described portion of the nervous system is grey matter.
