Question

Quizplus · Accepted Answer

The statement that is false is that the trophoblast is derived from the inner cell mass. In fact, the trophoblast is the outermost layer of cells in the blastocyst and is the first cell type to differentiate during embryonic development. The inner cell mass gives rise to the embryo and the other embryonic tissues. The other statements are true: the trophoblast secretes hyalouronidase, absorbs nutrients, has both an acellular and cellular component, and causes maternal blood vessels to break down.
