Meaning and Definition

A specific embryological process where epithelial cells spread over the surface of a developing embryo.

In broader biological contexts, it can refer to any process of enclosure or envelopment by spreading or migration of a cellular sheet over other tissues.

FAQ

Frequently Asked Questions

No, it is an extremely rare and highly technical term used only in specific biological contexts.

Absolutely not. Using it outside of embryology would be incorrect and confusing.

Emboly or invagination, where a cell sheet folds inward instead of spreading outward.

No. It is a specialised term for biologists. It is not required for general communication or standard tests like IELTS or TOEFL.

A specific embryological process where epithelial cells spread over the surface of a developing embryo.

Epiboly is usually technical (biology/developmental biology) in register.

Epiboly: in British English it is pronounced /ɪˈpɪbəli/, and in American English it is pronounced /ɪˈpɪbəli/ or /ɛˈpɪbəli/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Imagine a thin EPIdemic of cells spreading (like a blanket) over a developing baby (embryo) – EPIBOLY is the 'epidemic-like spreading' of cells.

Conceptual Metaphor

A SHEET SPREADING OVER A SURFACE. Cells are conceptualised as a continuous, flexible layer that expands to cover an underlying structure.
