The embryonic precursor to the central nervous system, formed when the flat neural plate of ectoderm rolls up and closes during neurulation (weeks 3-4 of development). The cranial portion forms the brain; the caudal portion forms the spinal cord. Failure to close causes neural tube defects such as spina bifida and anencephaly.

Understanding the term "Neural Tube" is essential for studying human anatomy because it provides precise language for describing body structures, their positions, and their relationships. Standardized anatomical terminology ensures clear communication among healthcare professionals, researchers, and students worldwide.
