Definition
Meaning and Definition
A protective, fluid-filled sac or thin tissue layer that surrounds and cushions a developing embryo in amniote vertebrates (reptiles, birds, mammals).
In a technical or metaphorical sense, any thin, protective initial layer or structure that encloses a developing entity in its earliest stages.
Dialectal Variation
British vs American Usage
Differences
No significant difference in technical meaning. 'Fetal membrane' is a common synonym in both, though 'embryonic' is more precise for early stages.
Connotations
Identical technical connotations. Potential metaphorical use is equally rare in both varieties.
Frequency
Extremely low frequency in general discourse, confined to professional/educational contexts in biology and medicine.

FAQ
Frequently Asked Questions
The amniotic sac is specifically the sac formed by the amnion, which is one type of embryonic membrane. So 'amniotic sac' is a subset of 'embryonic membrane'.
No. Only amniotes (reptiles, birds, and mammals) have true embryonic membranes. Fish and amphibians lay eggs in water without these specialized dry-land adaptations.
The condition and timing of the rupture of these membranes ('water breaking') is a key event in childbirth. Abnormalities in their development can cause serious pregnancy complications.
You can, but it will sound highly literary or scientific. E.g., 'The company was still wrapped in the embryonic membranes of its initial vision.' It emphasizes fragility and early-stage protection.
