Trilaminar Lining. The lateral plate mesoderm is the mesoderm that is found at the periphery of the embryoIt is to the side of the paraxial mesoderm and further to the axial mesodermThe lateral plate mesoderm is separated from the paraxial mesoderm by a narrow region of intermediate mesodermThe mesoderm is the middle layer of the three germ layers between the outer ectoderm and inner.
The mesoderm which is another layer of the trilaminar germ disc holds the tubes together and the lateral plate mesoderm the middle layer of the germ disc splits to form a visceral layer associated with the gut and a parietal layer which along with the overlying ectoderm forms the lateral body wall The space between the visceral and parietal layers of lateral plate mesoderm.

The most characteristic event occurring during the third week of gestation is gastrulation Gastrulation is a formative process by which the three germ layers which are precursors of all embryonic tissues and the axial orientation are established in embryos During gastrulation the bilaminar embryonic disc is converted into a trilaminar embryonic disc.
