The spelling of the word "cn viis" can be perplexing to many. However, once we break down the phonetic transcription, it becomes easier to understand. The word is actually the abbreviation for "cranial nerve six," which refers to the abducens nerve. The correct pronunciation would be [krē'nē-əl nerv siks], with the emphasis on the first syllable of "cranial" and on the second syllable of "abducens." While the spelling may seem unusual, it is simply a shorthand way of referring to a specific nerve within the human body.
