Morphology
ectoblast = ecto- + blast (semi-transparent) = ecto + blast
The term directly combines 'ecto-' (outer) + 'blast' (precursor cell) in a predictable way, but both elements are specialised combining forms that many learners will not know.
Etymology
The word ectoblast comes from Greek parts ecto- meaning 'outside' and -blast meaning 'bud' or 'young cell'. So the ectoblast is the outer layer of the early embryo that later becomes the skin and the nervous system.
