Outermost monolayer of cells surrounding the embryo that become very flattened in the blastula and give rise to the periderm. Sometimes used synonymously with periderm. Kimmel et al, 1995.[TAO]



taxon notes

Originally this tissue is one cell layer thick but in most vertebrates it soon becomes a two layered structure. The outer layer gives rise to the periderm.
