neurulation
Very LowAcademic / Technical (Biology, Medicine, Embryology)
Definition
Meaning
The embryological process where the neural plate folds to form the neural tube, which will become the central nervous system.
The key morphogenetic event in early vertebrate development, marking the beginning of nervous system formation.
Linguistics
Semantic Notes
A strictly technical, countable noun denoting a specific developmental stage. It is not used in general contexts.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or spelling. Both varieties use the term identically in technical contexts.
Connotations
None beyond its precise scientific definition.
Frequency
Extremely rare outside specialised fields in both varieties.

Context Usage
Academic
The primary focus of the paper is the molecular signalling pathways governing neurulation.
Technical
Proper folate intake is crucial to prevent neural tube defects arising from disrupted neurulation.
Examples
By Part of Speech
adjective
British English
- The neurulation stage is highly sensitive to teratogens.
- Key neurulation events were observed at day 20.
American English
- Neurulation processes are conserved across vertebrates.
- Researchers identified a critical neurulation gene.
Examples
By CEFR Level
- Neurulation is an important early step in the development of a baby's brain and spinal cord.
- Problems during neurulation can lead to serious birth defects.
- The precise folding of the neural plate during neurulation is driven by coordinated cellular movements.
- Genetic screens in model organisms have identified numerous genes essential for proper neurulation.
Learning
Memory Aids
Mnemonic
Think: 'NEURons start to form during neurULATION' – the 'U' in 'neurulation' can remind you of the tube shape being created.
Conceptual Metaphor
A 'rolling' or 'zipping-up' process to form a foundational tube.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'иннервация' (innervation). Neurulation is about formation, 'иннервация' is about nerve supply to tissues.
- The Russian term 'нейруляция' is a direct cognate, but its usage is equally confined to embryology.
Common Mistakes
- Using it as a verb (e.g., 'The tissue neurulates'). The verb form is not standard; use 'undergoes neurulation'.
- Confusing it with 'neurogenesis' (the birth of neurons), which happens much later.
- Spelling: 'neuralation' (incorrect) vs. 'neurulation' (correct).

FAQ
Frequently Asked Questions
No, it is exclusively a noun. The process is described as 'undergoing neurulation'.
The core concept is similar in vertebrates, but the specific mechanisms and morphology can differ between species (e.g., birds, mammals, fish).
Primary neurulation forms most of the neural tube from the folding of the neural plate. Secondary neurulation forms the lower-most part of the tube from a solid cord of cells that later hollows out.
Primarily in developmental biology, embryology, teratology (study of birth defects), and related medical fields like paediatrics and neurology.
