Cranial nerves are fundamental to neurology and medical education in both Brazil and the United States. The terminology is standardized internationally in medical practice. In clinical settings, healthcare professionals perform cranial nerve examinations (exame dos nervos cranianos) as a standard component of neurological assessments.
