1. Somite Development - Paraxial Mesoderm

Mesoderm lying right and left beside the notochord (axial mesoderm) forms the paraxial mesoderm as a pair of strips along the rostro-caudal axis of the embryo. This paraxial mesoderm will then commence to segment in pairs in a rostro-caudal sequence, the paraxial mesoderm in the head region will remain unsegmented.


Note - the cartoons show just the embryo righthand side mesoderm development (the same events occur on the lefthand side).
