neural tube
C2Technical/Formal
Definition
Meaning
The hollow embryonic structure that develops into the central nervous system (brain and spinal cord).
Any reference to this specific embryonic structure or its developmental abnormalities in medicine, biology, or related fields.
Linguistics
Semantic Notes
The term is used exclusively in scientific contexts to describe a key structure in vertebrate embryonic development.
Dialectal Variation

Common Mistakes
- Incorrect: 'neural tublar' or 'neural tubular'. Correct: 'neural tube'.
- Misuse in non-scientific contexts.

FAQ
Frequently Asked Questions
A neural tube defect (NTD) is a serious birth defect of the brain or spinal cord, such as spina bifida, that occurs when the neural tube fails to close completely during early embryonic development.
The neural tube forms and closes very early in pregnancy, typically between the third and fourth week after conception, often before a woman knows she is pregnant.
Adequate intake of folic acid (vitamin B9) before and during early pregnancy has been proven to significantly reduce the risk of neural tube defects.
No, it is a compound noun consisting of two words, often hyphenated when used attributively (e.g., neural-tube defect).
