Mesoderm Development

This animation shows the migration of mesoderm throughout the embryonic disc during gastrulation.
The pink arrow show how mesodermal cells spread out between the ectoderm and endoderm layers, forming the third (middle) layer of the trilaminar embryo.
Axial process - the arrow running from the primitive node upward is the axial process which will later form the notochord.
2 regions where no mesoderm is found, at the upper and lower ends of the gastrointestinal tract.

cranial (top) - buccopharyngeal membrane
caudal (bottom) - cloacal membrane.

Prechordal plate - lies above the buccopharyngeal membrane and is the cardiogenic mesoderm, that will form the heart.
