Example Sentences

Entoblast, en′tō-blast, n. the nucleolus of a cell.

Ectoblast and entoblast are the two primary germ-layers which arise from the invagination of the blastula; they are always the first to be laid down, and they can be directly referred back to a simple ancestral form, the Gastræa; they form the limits of the organism towards the exterior and towards the archenteron.

The parietal and visceral mesoblast, or the two middle layers, are always of later origin, and arise through evagination or plaiting of the entoblast, the remainder of which can now be distinguished as secondary entoblast from the primary.

In the gastrula stage, the segmentation cavity in which the mesoblast is formed lies between the entoblast and ectoblast.
