- ‘The yolk sac forms as the splanchnopleure surrounds the yolk.’
- ‘The splanchnopleure and somatopleure are each composed of different structures (derived from different germ layers).’
- ‘Mobilization of calcium from the yolk begins early in embryonic chickens and is facilitated by the calcium binding protein calbindin-D28K in endodermal cells of the yolk splanchnopleure.’
Late 19th century: from Greek splankhna ‘entrails’ + pleura ‘side’.
