Practice question

Go with B — Gray matter. Within Peripheral Nervous System, that statement lines up with the standard definition and the usual exam wording you’ll see. In plain terms, location matters here: Gray matter is the structure or site that matches the description. Holding that picture in mind makes Gray matter feel natural rather than something you only memorise. Link the term to a real body example (organ, tissue, or ion flow) so the idea stays concrete under exam pressure. A short mental diagram helps — start from stimulus or structure, follow the pathway, and stop at the functional result described by Gray matter.
