What is the Suprasternal space?

How is Buccopharyngeal membrane formed?
It is created from the cranio-caudal and lateral folding of the embryo, resulting in the incorporation of one portion of the endoderm-lined yolk sac into the embryo to form the primitive gut. The other two portions of the endoderm-lined cavity, the yolk sac and the allantois, remain outside of the embryo.
