Naming ability is linked to which fiber tract?

• A. Angular gyrus
• B. BA 39
• C. Arcuate fasciculus
• D. Anterior superior temporal gyri

Answer: (C)

Naming depends on linking what you know about a concept with how you say the word, a process that relies on the dorsal language pathway connecting language comprehension regions to speech production areas. The arcuate fasciculus carries phonological information between Wernicke’s area in the posterior temporal lobe and Broca’s area in the frontal lobe, enabling phonological encoding and the articulation of lexical items. If this tract is compromised, the bridge between understanding a concept and producing the corresponding name weakens, leading to naming difficulties. The angular gyrus and anterior superior temporal regions are important for broader semantic processing, but naming performance specifically hinges on this dorsal connection between comprehension and production areas—the arcuate fasciculus.
