These three layers, the endoderm, the ectoderm and the mesoderm, are called the primary germ layers. After gastrulation, the cup-like embryonic stage that contains at least two distinct germ layers is called the gastrula.n mammals, gastrulation is achieved in a very different way. This is because the outer layer of the mammalian blastocyst, which is roughly equivalent to the blastula, becomes the mammalian placenta and is not available to create the primary germ layers of the embryo.
I think the Wolfram System is the term now used to describe what we currently think of as Mathematica. The term Wolfram Language is the language in which you write code in the Wolfram System, or what we currently call (loosely) the Mathematica language, rather than the whole shebang - FrontEnd, Kernel, etc.. Still, that's just me guessing - I know nothing. :) â cormullion Nov 26 '13 at 20:18.
